Trang 91 Introduction
Whenever radioactive materials or other radiation sources areused, appropriate training of the worker is required NCRP Report
No 127, Operational Radiation Safety Program (NCRP, 1998), sets
forth the basic elements of an ionizing radiation safety program.Training of employees who may be exposed to radiation in thecourse of their work was cited as a necessary part of such a pro-gram All radiation hazards and the related training programsdesigned to control exposures to both ionizing and nonionizingradiation should be presented as part of the overall occupationalhealth and safety program Although this Report focuses on radia-tion safety training, it is important for a training program toinclude information about all occupational hazards that might beencountered This will allow judgments regarding radiation haz-ards to be made in perspective with the other hazards that might
be present
Training rather than education is the subject of this Report Asthe term is employed herein, training is linked to the instructionand practice that are required to develop job-related skills or modes
of behavior, while education, which may include training, impliesachievement of a greater degree of understanding Although onemight consider it desirable to educate the worker, practical consid-erations limit the total number of workers who can be educated inthe formal sense On the other hand, scientists and engineers,whose work involves ionizing or nonionizing radiation, may havereceived such training as a part of their education; however, train-ing for specific job requirements may also be necessary for theseindividuals
There are at least four important reasons for training First, thedevelopment of worker skills through training enables the individ-ual to perform tasks efficiently and with confidence Second, whenindividuals are aware that there is some risk associated with theirexposure, they can become active participants in the decision toaccept and, where possible, to reduce such risk as part of their job.Third, the number and seriousness of accidents can be reducedthrough training Fourth, workers, who are properly trained, will
be aware of the regulatory requirements associated with their
Trang 102 / 1 INTRODUCTION
activities that involve radiation or radioactive material Thus, anemployee trained for both routine and nonroutine situations ismore likely to assist in maintaining all exposures as low as reason-ably achievable (ALARA)
The scope and depth of radiation safety training will vary icantly with the job requirements and the responsibilities of theemployee For the radiologist's secretary, a brief description ofthe working environment, the risks and protective measures may
signif-be sufficient In such uncomplicated situations, on-the-job trainingmay be all that is necessary For persons involved in reactor opera-tions, fuel fabrication, or decommissioning, an extensive, struc-tured training program will be required However, the basicprinciples and practices of training are common to virtually allclasses of employees This Report emphasizes these principles andpractices and provides guidance for the development of the totaltraining program
Although it is not a detailed training manual, this Report isintended to provide senior management personnel with a usefulsummary of the needs and requirements of training programs Pro-fessional health physicists and trainers will find useful informationfor the development, conduct and evaluation of their training pro-grams Professional trainers will find useful information in support
of their programs A private physician using a diagnostic x-raymachine, or an individual scientist working with small quantities
of radioactive materials, may find this Report contains more mation than required Nevertheless, the general philosophy andspecific training concepts will be useful
Trang 11The success of a radiation safety training program depends to alarge extent on management commitment Employees can readilydiscern the degree of this commitment to the training program in
many ways (e.g., organization of the training program, condition of
training facilities, competence of training personnel, the prioritygiven to the training, time allotted for training, expectations ofemployee involvement) It is important that management keepoperational requirements from interfering with the training pro-gram and ensure that adequate funding and sufficient trainingtime are provided and that the importance of training is conveyed
to supervisors and staff
2.2 Qualification of Trainers
Qualification requires that trainers have a sound ing of the radiation safety subjects that they teach Trainers shouldhave a combination of academic courses, on-the-job training, andpractical experience in those subjects that is sufficient for them toconfidently answer questions on theory, applications and rationale
understand-If the material presented is to be directly applied by the trainee insuch areas as operations, instrumentation, shipping, etc., theinstructor should have appropriate experience in the specific
Trang 124 / 2 MANAGEMENT’S RESPONSIBILITY
application It is recommended that trainers themselves receivetraining in instructional methods Competent trainers are essen-tial if a training program is to lead to satisfactory performance bythe trainees
In some organizations a single individual may be responsible forthe overall training effort Such an individual must have therespect and confidence of management and must be delegated ade-quate responsibility and authority to administer and manage thetraining program effectively In these programs, it is vital thatthe responsible individual be dedicated to training and under-standing of the various organizational needs that training can ful-fill Further, this person should be able to manage, plan and projectfuture needs; select qualified staff; and utilize personnel effectively.The training organization should be versatile and flexible so thatthe emphasis can be changed easily and efficiently to meet theneeds of the facility's operations
In other organizations, the training responsibility may beshared among responsible members of the radiation safety staff Insuch organizations the qualification requirements should be met byeach of the individual trainers
2.3 Evaluation
Management has the responsibility to evaluate the performance
of the trainers and to provide feedback that will help to modify thetraining program as appropriate Review of training objectives,evaluation of the learning environment, and funding are also part
of this effort This evaluation should determine the effectiveness ofthe training staff, its responsiveness to feedback, the cost-effectiveness of the program, and areas requiring improvement
2.4 Records
A system for maintaining training information can be used toevaluate the adequacy of the program, establish an inventory ofemployee skills, and delineate the additional needs of the workers.Appropriate records should be kept to document classroom train-ing, on-the-job training, demonstrations, and other training activi-ties They should include course descriptions, dates on whichcourses were given, attendance, and results of any examinations.Course materials should include sample copies of all lesson plans,worksheets, examinations, problem sets, etc., as well as results of
Trang 132.4 RECORDS / 5
audits and evaluations of all training activities A record of eachtrainee’s performance should be retained and be available to thattrainee Student evaluations of the course and the instructorshould be included in this collection
A repository for records may be necessary for a specified perioddepending on legal requirements These records must be in order,complete, and easily retrievable Further information on recordrequirements is found in NCRP Report No 114 (NCRP, 1992)
Trang 143.1 The Potential for Radiation Exposure
Potential exposure of employees can usually be estimated beforethe work starts The higher the potential exposure, the moredetailed and comprehensive are the training requirements Thenature of the potential exposure, such as from airborne radioactivematerials, surface contamination, devices, or sources, will alsocontribute to determining the content and depth of the trainingprogram
3.2 The Complexity of the Task
Some tasks are more complicated than others and require siderably more training to assure that the job can be completedsafely and competently, and that the associated radiation exposurecan be maintained ALARA Other site-specific hazards associated
con-with the radiation safety program (e.g., heat stress and
anti-contamination clothing use, handling infectious radioactivepatients, obscured vision when wearing full-face respiratory pro-tection, etc.) should be considered
3.3 Regulatory Requirements
There may be state or federal regulatory requirements which
will influence the structure and content of training (e.g., females of
reproductive age, training for radiographers, etc.) Managers and
Trang 15phys-• Personnel who are directly and continuously supervised willnormally need less training than those who work indepen-dently or who have infrequent supervision.
• Individuals who are responsible for the supervision ofothers will usually require more training
• Individuals who have received previous training mayrequire only site-specific additional training Care must betaken to assure that the previous training is current andapplicable to the needs of the employee's present positionand has been retained
• Individuals who have personal concerns about radiationmay need special attention
• The training program should be responsive to specificemployee concerns
Trang 164 Personnel to be Trained
All individuals who, in the course of their occupation, areexposed to radiation levels above those of the general natural back-ground at the surface of the earth should receive radiation safetytraining This includes individuals who visit or work in a facility inwhich radioactive material is handled or radiation-producingdevices are operated It also includes individuals who may beexposed to enhanced radiation levels from sources that are gener-
ally considered to be natural, e.g., cosmic rays Individuals
associ-ated with a radiological environment should be provided a level oftraining commensurate with the nature of their responsibilities,their potential exposure, and other potential hazards Appendix Aspecifies the essentials that should be covered
Some workers have an increased potential for exposure due to
their job assignments (e.g., they handle radioactive materials or
operate radiation-producing equipment) Other workers may beonly incidentally exposed to radioactive materials or radiationsources Individuals should be classified based on their workassignments and responsibilities, potential for exposure, and rela-tionship to the facility
4.1 Employees 4.1.1 Radiation Workers
Radiation workers are individuals who:
• have significant potential for exposure to radiation in thecourse of their work assignments, or
• are directly responsible for or involved with the use and trol of radiation sources or radioactive materials
con-These individuals generally are subject to routine personnelmonitoring Employees in this category will generally be required
to have extensive training, which will vary depending upon thenature of their jobs For example, one may want to distinguish
Trang 174.1 EMPLOYEES / 9
between individuals (a radiochemist or a radiographer) whosework assignments involve the use of radioactive material or radia-tion-producing devices and other individuals (skilled craftsmen or
maintenance personnel, e.g., a person working on contaminated
ductwork) whose work assignments may require their working in aradiation field
As a minimum, the subject matter presented in Appendix Ashould be considered in developing a training program The timerequired to conduct the training program may range from a fewhours to several days depending on the factors listed in Section 3and, particularly, on the need for job-specific training
4.1.2 General Employees
Some individuals can be identified who do not work routinelywith radioactive material or other radiation sources, but whoseduties may occasionally bring them into areas where radiationexposure can occur These may include stockroom personnel, ship-ping clerks, secretaries, nurses, students, and housekeeping staff.However, where the involvement is more than sporadic, it is rea-sonable to classify such individuals as radiation workers Theclassification must be based on frequency, duration, level of super-vision, and the potential magnitude of exposure
Individuals categorized as “general employees” will normallyneed at least one, but less than four hours of radiation safety train-ing Many of the topics in Appendix A can be treated in less depthfor this group than for radiation workers However, a specific effortshould be made to assure that individuals in this category areaware of the level of their radiation exposure, understand its rela-tive importance, and learn how to control their own exposure Indi-viduals can be unduly concerned about low levels of exposure and
be fearful of their work environment if an appropriate perspective
is not established
4.1.3 Management and Supervisory Personnel
Managers and supervisors should be classified in one of the twocategories described in Sections 4.1.1 and 4.1.2 Radiation safetytraining is important for such individuals insofar as it may affectthe activities, safety and training of personnel they supervise
Trang 1810 / 4 PERSONNEL TO BE TRAINED
4.1.4 Radiation Safety Personnel
The professional and technical radiation safety staff will ally be classified as radiation workers They require additional aca-demic education and practical training in order to direct, assessand train others in the implementation of the facility’s radiationsafety program Training for radiation safety technicians must becommensurate with the hazards and jobs performed at the specificfacility
gener-4.2 Contractor Personnel
Many facilities make use of individuals who are employed bycontractors and who are assigned to a facility for a period of time toperform specific tasks This category may include laborers, mainte-nance workers, craftsmen, technicians, security personnel, consult-ants, and others Contractor personnel should be provided withtraining commensurate with the potential hazards Their trainingshould be similar to that for regular full-time employees working inthe same conditions Review of a contractor employee's trainingexperience with current and previous employers should be consid-ered in determining the training requirements for this individual
4.3 Females of Reproductive Age
Females of reproductive age can be allowed access to, andemployed in facilities in which the potential exists for exposure toradiation, but they should be informed and made aware of the level
of risk associated with their potential exposures However, itshould be noted that special regulatory limits may apply to this cat-
egory (e.g., for ionizing radiation) (NRC, 1999c) Further
informa-tion on recommendainforma-tions for the protecinforma-tion of the embryo/fetus arecontained in NCRP Report No 116 (NCRP, 1993a) and NRC Regu-latory Guide 8.13 (NRC, 1999c)
4.4 Visitors
Visitors include individuals who enter a facility, usually briefly,
as part of a tour group, personnel who service utilities and support
Trang 194.5 MINORS / 11
equipment, or as a representative of a delivery or messenger vice They could include individuals who are conferring withemployees for either short or extended periods of time Visitors whoare under the constant supervision of escort personnel can be pro-vided access after receiving training to meet the minimum require-ments, which could include the following instructions:
ser-• they may be near radioactive material or producing equipment
radiation-• they must follow the instructions of the escort personnel
• they must wear the dosimetry device as required bythe facility policy
• they may choose to decline the opportunity to visit thefacility
In any case, the individual should be informed and made aware
of the level of risk associated with the potential exposure
Individuals who enter a facility in a professional capacity ing scientists, experimenters from other research facilities, con-sultants, student trainees, etc.), who are assigned to the facility for
(visit-an extended period of time, need to be classified (visit-and trained in amanner comparable to regular employees (Sections 4.1.1 and4.1.2) In universities, government laboratories, and certain indus-trial facilities, students may be engaged in educational or trainingactivities that can result in radiation exposure Radiationtraining commensurate with the potential exposure should be pro-vided to these individuals before they are permitted to work inareas where they may be exposed to radiation
4.5 Minors
Minors (under 18 y of age) may be permitted access to facilities
in which the potential exists for exposure to radiation However, itshould be noted that special regulatory limits may apply to minors(NRC, 1999a) They and their parents or guardian should beinformed and made aware of the level of risk associated with thepotential exposure In addition to these regulations, individualfacilities may impose additional restrictions on minors Furtherinformation on recommendations for the protection of minors ispresented in NCRP Report No 116 (NCRP, 1993a)
Trang 2012 / 4 PERSONNEL TO BE TRAINED
4.6 Emergency Personnel
Many facilities have procedures and plans dealing with the ious types of emergencies specific for their facilities (fire, medical,chemical, natural disaster, radiological, etc.) Guidance for develop-ing radiation emergency plans is presented in NCRP Report
var-No 111 (NCRP, 1991) Coordination and training of emergencyresponse personnel enhances their effectiveness Some facilitiesmay have regulatory requirements to establish a radiological emer-gency response plan, which includes training requirements foremergency response personnel, both from within and from outsidethe facility
4.6.1 Pre-Emergency Training
In emergency situations, a facility may need assistance fromfire, police and medical personnel, who may be regular employees,contractor personnel, or simply “volunteers” available from anearby location (city, hospital, etc.) Although these individuals arewell trained in their specialty, they may not be familiar with per-forming those functions in areas where radioactive materials areroutinely handled, or where radioactive contamination may bepresent Also, they may not have experience with treating individ-uals potentially contaminated with radioactive materials or thathave received a significant radiation exposure To assist them inmeeting their responsibilities in emergency situations the facilitymanagement should provide training specific to the radiation haz-ards they may encounter In general this training should include adescription of the types of radiation hazards at the facility, physicalproperties of the radioactive materials, inventories and quantities
of radioactive material, existing contamination levels, the possibleeffects associated with potential accidents, and the use of emer-gency radiation detection equipment The goal is to provide suffi-cient training to permit informed judgments in emergencysituations
4.6.2 Post-Emergency Training
It is acknowledged that there may be emergency situations that
do not allow the training of emergency personnel prior to arriving
at the facility In these cases, emergency personnel should beallowed access under the supervision of radiation safety personnel
in order to perform their responsibilities This will allow for the
Trang 214.8 ENGINEERING PERSONNEL / 13
appropriate medical care to be given to injured individual(s) andallow for mitigation of loss of property At the conclusion of theemergency, the radiation safety staff should initiate discussionswith emergency personnel involved to ensure that they areinformed and aware of the level of risk associated with their expo-sures Additionally, training sessions should be scheduled to ensurethat emergency personnel are aware of the full spectrum of thetypes of radiation hazards at the facility, the possible effects asso-ciated with potential future accidents involving the radioactivematerials, and the use of radiation detection equipment
4.7 Special Situations
At times, special situations may arise in which certain uals need additional training of a specific nature Individuals inthis category include: (1) workers who are required to enter unusu-ally high radiation fields, (2) family members who are required toassist a patient during medical procedures, or (3) patients who arereceiving radiation for a medical procedure and their family mem-bers [see NCRP Commentary No 11 (NCRP, 1995)] These individ-uals should be informed and made aware of the level of riskassociated with their exposures
individ-In addition, Situation 1 may require special training for ducting procedures rapidly, but safely together with other specialemergency procedures that may be imposed Mock-ups anddry-runs may be particularly useful in this case This training ismost effective when performed immediately before the operation
con-4.8 Engineering Personnel
All engineering personnel whose work assignments require thatthey design facilities in which radioactive material is handled orradiation-producing devices are operated should receive radiationsafety training These personnel include those who develop plans todeactivate or decommission a facility in which radioactive materialwas handled Although these engineers will not themselves beoccupationally exposed, the results of their efforts can impact theexposure of other employees
Engineering employees may include civil, mechanical, electricaland nuclear engineers, architects, designers, and others Radiationsafety training will vary significantly with the job requirementsand the responsibilities of the engineering employee For the
Trang 2214 / 4 PERSONNEL TO BE TRAINED
mechanical or electrical engineer or designer, an understanding ofradiation, radiation effects, radiation risks, and protective mea-sures may be sufficient for the selection of equipment for applica-tions in radiation areas For the civil engineer or designer andarchitect, an understanding of radiation, radiation effects, radia-tion protection considerations, radiation risks, and protective mea-sures may be sufficient for providing engineered features to reduceradiation exposures In such uncomplicated situations, on-the-jobtraining may be all that is necessary For nuclear engineering per-sonnel, an extensive and structured program covering radiationhazards and radiation safety is provided as part of their education
Trang 23This Section identifies the major elements for the development
of a radiation safety training program The approach consists of thefollowing six sequential steps which are applicable, in principle, to
any type of training: (1) perform a job task analysis to determine
the knowledge, skills and attitudes necessary to perform a task at
the desired level of competence; (2) design and develop the training,
including the development of training objectives, establishment
of testing criteria, and development of the course structure;
(3) develop a lesson plan and training materials; (4) develop an
evaluation plan along with the lesson plan; (5) conduct the tion; (6) evaluate and feedback results to ensure that the original
instruc-standards of performance are met and maintained The trainingprocess is normally cyclic since the evaluation and feedback, aswell as the need for retraining, can lead back to Step One Each ofthe six steps will be developed in the following sections Practicalexamples, including one for a small facility with simple require-ments and one for a large facility with multiple safety programs,are given in Appendix B
In many situations, only the rudiments of such a formalapproach will need to be employed The degree of adherence to theentire program as developed below will depend upon the magni-tude and complexity of the radiation hazards While a trainershould strive for the level of completeness this Section suggests,practical considerations will lead to some simplifications
5.2 Step One: Job Task Analysis
Specific tasks related to the work assignment are defined andanalyzed to determine the level of competence required to workwith, or around, radiation sources Following this, the necessary
Trang 2416 / 5 DESIGN AND DEVELOPMENT OF A TRAINING PROGRAM
supporting skills, knowledge and attitudes are identified Eachtask, together with its supporting requirements, determines thefocus of a training effort For complex jobs, this evaluation may be
quite lengthy, with many tasks and subtasks involved (e.g., see
• the nature of the radiation hazards to be encountered
• size of group to be trained
• type of skill, knowledge and attitude to be attained
• previous experience and training of the workers
• the budget and staff available for training
5.3.1 Training Objectives
Once the general scheme of the training program has beendetermined, the objectives for each selected task or subtask aredeveloped Each objective should be defined in such a way that thetrainee, upon successful completion of the course, will be able todemonstrate the acquired knowledge, skill and attitude Eachobjective should contain information on the degree of accuracy,time limitations, and other conditions under which the individualshould perform each required task As objectives are developed,they should be documented and correlated to each task so that anymodification of a task can be evaluated within the context of thetraining system
5.3.2 Testing Criteria
The next goal within the training analysis is to establish thetesting or evaluation criteria to be used in measuring successfulcompletion of the objective These criteria might consist of a writ-ten examination to demonstrate knowledge and to determine infor-mation retained, or a practical test to demonstrate skill and theability of the trainee to perform the required task Althoughthe testing criteria for each task must be developed at this stage in
Trang 255.4 STEP THREE: LESSON PLAN AND TRAINING MATERIALS / 17
order to proceed logically with the course structure, the overallapproach to testing and evaluation is discussed in Section 5.5
5.3.3 Course Structure
The next step is to develop an effective integration of the coursecontent with the method of presentation Basic perspectives onradiation risk and overall risk management should be integratedinto the course structure Topics for a training program can befound in Appendix A Appropriate teaching techniques are dis-cussed in Section 6
The course structure establishes a logical sequence, whichwould then indicate the necessary background of knowledge andskills and the preferred instructional methods The structureshould also allow for self-evaluation by the trainee and for programevaluation by both the trainee and trainer
5.3.4 Summary Analysis
The last step in the design and development of a training gram is to prepare a summary analysis sheet on the course struc-ture Such a summary analysis should include the followinginformation:
pro-• the primary task being taught
• the objectives of the course
• a listing of the major requirements (either by subtask,knowledge, skills, attitudes, subjects, demonstrations, etc.)
• the testing criteria
• the supporting material
• the instructional methods
• a listing of audiovisual aids and other necessary equipmentand materials
• an estimate of the time required to accomplish the training
5.4 Step Three: Lesson Plan and
Trang 2618 / 5 DESIGN AND DEVELOPMENT OF A TRAINING PROGRAM
Examples of lesson plans are presented in Appendix B Sources oftraining materials and aids are presented in Section 6 The criteriafor evaluation of the effectiveness of the training program should
be included in the lesson plan
5.5 Step Four: Evaluation Plan
The evaluation plan should be developed concurrently with thelesson plan, primarily to ensure consistency The criteria for evalu-ation should be included in the lesson plan Evaluation shouldassess the degree of learning, the retention of information, and,ultimately, the accomplishment of the training objectives The eval-uation plan, together with the developed training material, should
be reviewed to ascertain that the trainee is being taught each tive and is being tested on performance
objec-There are several types of evaluations These include: (1) tion evaluation, (2) learning evaluation, (3) performance evalua-tion, and (4) results evaluation
reac-A “reaction evaluation” is usually given immediately followingsome learning activity; it serves to provide immediate feedbackconcerning the likes and dislikes of the trainee and can be used toimprove the presentation
A “learning evaluation,” i.e., a written or oral test, is usually
given to determine the amount of knowledge retained This is cially useful if the same evaluation is performed both before, imme-diately after, and at some later time following instruction It allowsdetermination of the amount of knowledge learned and thenretained over a period of time
espe-The “performance evaluation” is a behavioral test If this ation is based on the specific job requirement, it determines effec-tively the skills and attitudes of the trainee and the success of atraining process
evalu-A “results evaluation” is used to determine the success or failure
of training The criteria can be productivity, but it can also be dent rate, collective effective dose, etc Results may be influenced
acci-by many factors and they must be analyzed carefully to determinewhat effect, if any, training has had In such evaluations, supervi-sors may provide useful input
Trang 275.8 RETRAINING / 19
5.6 Step Five: Instruction
The success of the planning effort depends on the quality ofinstruction (see Section 2.2) Instructors should be individuals whoare experienced in teaching and who have adequate knowledge ofthe subject A well-planned program needs good instruction to suc-ceed Demonstrations and “hands-on” training may be valuable, oreven essential, for certain types of instruction Some classroominstruction can be replaced effectively by using interactivecomputer-based training programs
5.7 Step Six: Evaluation and Feedback
The last step in the sequence is evaluation and feedback Thisstep consists of the continual evaluation of performance on the job
to provide feedback that will help to modify the training effort asappropriate Evaluation of instructors and audiovisual programs,validation of specific job requirements, review of training objec-tives, addressing individual concerns, evaluation of the learningenvironment to support training, budgeting, etc., are also part ofthis effort Additionally, a performance feedback program should beincorporated in this step Examples of performance feedbackinclude supervisors’ evaluation of work performance, review andevaluation of radiation survey and exposure records, and incidentreports All these factors should be used to determine whether thetraining is satisfactory, effective, responsive to feedback, andcost-effective, as well as to indicate areas requiring improvement
• retesting at periodic intervals to determine proficiencyretention (performance related, where possible)
• interviews with workers, supervisors and technical staff
to collect and review data on job performance

Trang 296 Learning Environment and Training Aids
For a training effort to be successful, the trainee who fully completes the course must become more knowledgeable aboutradiation safety and more effective in applying this knowledge topractical situations Various methods for communicating informa-tion can be effective with proper planning and implementation.There are several basic training formats: individual or personalstudy, large group instruction, mentoring, and on-the-job training

Individual study is an effective way to acquire knowledge such
as mastering the basic fundamentals in a science Materials andprocesses that can be used may include: programmed learningtexts and other printed material, interactive computer systems,videotape, slides, and film A self-instruction program requiresskillful design by someone with detailed knowledge and experienceconcerning the necessary reinforcement of the typical trainee'sresponse The training can be decentralized, unscheduled,self-paced, self-evaluated, and self-reinforced Individual study can
be supplemented by encouraging the exchange of ideas and tions between a good trainer and a few course participants In allcases trainees should have the opportunity to discuss the traininginformation and to ask questions It is also important to provide forevaluation and feedback as described in Section 5.7 when develop-ing individual study programs

6.2 Group Instruction
Large group instruction is satisfactory if the objective is simply
to acquire knowledge or to develop interactive and team building
skills (e.g., teamwork for emergency responders) This is especially
true when the program includes the opportunity to practice thoseskills in laboratories and exercises If the objective is primarily toenhance understanding and develop skills, smaller discussiongroups are better The instructional formats for larger groups aretypically lectures, films, slide presentations, symposia, field trips,group interviews, and videotape
6.4 On-the-Job Training
On-the-job instruction is most useful when high degrees of skilland constant reinforcement are required Skill training should bemoved out of the classroom and into the job site where the condi-tions are real and where opportunity for repeated practice over anextended period is available In some situations, models ormock-ups of the job site will be required because of the potential forradiation exposure or nonradiological hazards On-the-job trainingrequires skillful design and evaluation with a commitment frommanagement and the trainee

6.5 Training Aids
Many trainers use visual supplements such as overhead tors, computer-based projection, slides, videos, filmstrips, etc., asaids in presenting information efficiently and succinctly With closeattention to maintenance of a personal relationship between thetrainer and the trainees, visual supplements can reinforce the com-munication of information There is an abundance of commerciallyavailable software that can be used for radiation safety training Videotape programs are commonly used as a communicationsmedium in technical fields Imaginative programming can makevideotape very effective, especially for self-instruction On theother hand, when these programs are no more than a recording of
projec-a lecture, they mprojec-ay be only mprojec-arginprojec-ally effective
Videotape or computer-based programs can be used as ments to the classroom environment or as methods in which thetrainee interacts with the teaching program without benefit of apersonal instructor Similarly, a number of slide and audiotape pre-sentations and self-paced instructional manuals have been devel-oped as aids to learning
supple-6.6 Training Environment
The training environment is quickly evolving as new technologybecomes available Students now have more flexibility in determin-ing the manner in which they may choose to learn They may optfor a traditional training environment such as a formal classroom
or one of the many new styles of learning that are rapidly evolving New technologies, including distance learning based on videoconferences from universities or other training centers, permit avariety of options that were not previously available These samesystems can be used within an institution to disseminate informa-tion without requiring the assembly of people at one location Addi-tionally, the Internet is a constantly expanding source forinformation on training resources However, it is important to rec-
ognize that many of the resources available via the Internet may
not have been carefully evaluated
No matter what style of training program or environment isselected, it is important to employ a feedback mechanism to mea-sure the competency of the individual to perform the job functionfor which he or she is responsible
Trang 327 Audit
Periodically, management should have the training programaudited to ensure that training objectives are being fulfilled Theaudit could be performed either internally or by an outside consult-ant The auditors should look for:
• defined objectives for the training program
• relevance of the program
• currency of the program
• the quality of the program
• the availability of feedback both at the end of the trainingand after on-the-job experience
• management commitment and resources for the trainingprogram
• frequency and duration of training
• requirements for retraining
Trang 33“Essential elements” are those topics that should be included inall radiation safety training programs The extent of instructionand its technical content should be adjusted depending on the workassignments of the staff being trained.
“Optional elements” are those topics that should be consideredfor inclusion in the training program These depend on the types
of operations conducted at the facility and the work assignments ofthe staff

Although all three of these examples are skill oriented, thissame approach can also be employed to acquaint radiation workerswith an understanding of the risk associated with their radiationexposure The discussion that follows is presented in accordancewith the steps described in Section 5
B.1 Secretarial Support Staff in a Small
Medical Facility B.1.1 Introduction
For purposes of this example, it is assumed that the secretarialstaff have all the required secretarial skills, but are not trained inthe radiation safety requirements of their work
B.1.2 Step One: Job Task Analysis
The secretarial staff ’s responsibility from a radiation safetystandpoint might be identified in our example as “observing a pro-hibition against entering controlled areas, namely x-ray roomsand/or radionuclide preparation and administration areas.”With the task established, the supervisor can now prepare astandard of performance that describes its successful accomplish-ment In this example, it is necessary “to recognize the caution sign
Trang 37B EXAMPLES OF THE TRAINING METHOD / 29
for controlled areas and not to enter such an area under normaloperating conditions.”
With this standard of performance, the supervisor can identifythe skills, knowledge and attitudes necessary to accomplish thetask In this example, these attributes are simply the ability to readand recognize the sign, to understand the significance of not enter-ing the area, to identify normal conditions, and to know the proce-dure if entrance to the area is necessary
In addition, the secretarial staff should understand the hazardsand risks that exist in controlled areas and that the areas normallyoccupied are safe These skills, knowledge and attitudes becomethe basis for determining the content of an instructional method fortraining
B.1.3 Step Two: Training Design and Development
Even in a small facility, there can exist a variety of instructionaloptions In this example, the medical facility can easily provide aslide or tape program using in-house slides of signs and procedures.Although a special instructor might be engaged to train the secre-tarial staff on an occasional basis, the training might better be per-formed by the medical staff In either case, the individualperforming the training should have knowledge of the job taskanalysis (Step One) and maintain consistency with the trainingobjectives In the example, the training objective can be stated as
follows: At the completion of this instructional period, the trainee
should be able to identify quickly the standard controlled-area warning signs used at this facility and to distinguish them from other standard warning signs.
The next step within the training analysis is to establish thetesting criteria which will determine whether the training objec-tive has been accomplished successfully In this example, properrecognition of warning signs may be all that is needed
The final step in the training analysis is to develop the sary course structure to accomplish the desired training In thisexample, the following two conditions are assumed:
neces-• The supervisors of the secretarial staff will conduct thetraining since professional trainers would not normally beneeded
• The training materials are in the form of printed loose-leafbinders with full-color photographs of signs and areas
Trang 3830 / APPENDIX B
The supervisor instructs the staff members on the meaning of eachwarning sign, encourages review of training materials both pre-and post-test, and provides periodic reinforcement
A summary analysis of the course structure might be as shown inTable B.1
B.1.4 Step Three: Lesson Plan and Training Materials
Training materials to support this training effort might consist
of photographs, typed pages, binders, pre- and post-tests, and ation survey data The training materials could be prepared by thesupervisor or by training consultants
radi-A lesson plan could be as follows:
B.1.5 Step Four: Evaluation Plan
The evaluation plan for this training program consists of testingthe trainee both before and after instruction to determine knowl-edge of signs and actions The supervisor will reinforce properactions in the work area after the participants have observed initialdemonstrations
