en ironmental radiation levels in the neig b rho d of these faci ties

The evaluation of the en ironmental radiation dose from photon is dif f ic lt The comp sition

of the b c grou d radiation is complex an in lu es contribution from natural sources s c

compl cated by the variation in the natural b c grou d radiation dose, varies in time d e to

variation in ambient radon con entration an sp ce d e to sp tial heterogeneity of the

natural en ironmental b c grou d

The req irements sp cif ied in this stan ard relate to normal o eration of the as embly

Should an as embly b req ired f or emergen y con ition on-site at n cle r f aci ties then the

to overlo d c aracteristic The req irements for p rta le work place monitors to me s re
