Question 446: In this example, an individual has worked at
the licensee's facility earlier in the current year and was
required to be monitored because the individual accessed a
high radiation area. During this period, the individual's
monitored dose did not exceed 10% of a limit. Now the
individual is performing other work at the licensee's
facility in the restricted area, but no longer has access
to high radiation area. An evaluation based on the
individual's new job scope shows that the individual is not
likely to exceed 10% of a limit for their entire period of
work during the year at the licensee's facility. (a) May
the personnel dose monitoring of the individual be
discontinued on the basis that the individual is not likely
to exceed 10% of a limit and the individual no longer has
access to high radiation areas? (b) If so, must the
individual's dose monitoring results, acquired during the
period of required monitoring, still be reported in
accordance with ยง20.2206 "Reports of Individual
Monitoring"? The purpose of these questions is to
determine under what conditions required individual
monitoring may be discontinued as no longer required.
Answer: (a) Yes. (b) Yes. (References: 10 CFR 20.1502,
10 CFR 20.2206).
