Health Physics Questions and Answers - Question 446

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 §20.2206 "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.
