4.24 SEALED SOURCE CONTAMINATION i
i lhe limitations on removable contamination for
?
sources requiring leak testing, including alpha
{
emitters, is based on 10 CFR 70.39(c) limits for j-plutonium. The limit is consistent with Section E.105 of the " Rules and Regulations for Protection Against Radiation" (September 29, 1976 edition) developed and adopted by the Illinois Department r
of Public Health. This limitation will ensure that leakage from byproduct, source, and special
[.
nuclear material sources will not exceed allowable l'
intake values.
Sealed sources are classified into three groups
[
according to their use, with surveillance i
requirements commensurate with the probability of F
damage to a source in that group.
Those sources L:
which are frec.uently handled are required to be f
tested more often than those which are not.
U Sealed sources which are continuously enclosed II:
within a shielded mechanism (i.e., sealed sources b
within radiation monitoring devices) are di considered to be stored and need not be tested I[
unless they are removed from the shielded I?
mechanism.
