Question 214: (a) If the individual had not been

monitored at his previous employer while receiving an

occupational dose (i.e., the dose there had been determined

not likely to exceed 10% of the limits), and the current

employer, Licensee Z, determines in advance that the

worker's annual dose for both licensees will exceed 10%

(although the dose at Licensee Z will not exceed 10%), must

Licensee Z monitor for external dose? (b) If the

individual worked for several previous employers during the

year, some who badged and some who did not, and Licensee Z

makes a prospective determination that its own activities

will result in a dose less than 10%, must Licensee Z

monitor for external dose?

Answer: (a) No. The criteria to determine whether

monitoring is required is independent of exposures received

at any other place of employment prior to or subsequent to

employment with Licensee Z.

b) No. (Reference: 10 CFR 20.1502, 10 CFR 20.2104,

Regulatory Guide 8.34)
