Question 114: A licensee is required to provide individual
monitoring for each occupationally exposed individual who
is likely to receive, in a year, a dose in excess of 10% of
the applicable limits in 10 CFR 20.1201, 10 CFR 20.1207, or
10 CFR 20.1208. Must a licensee account for the exposure
that an individual may receive at another licensee's
facility, if that worker transfers to another licensed
facility during the monitoring year, when determining if it
is likely that the individual may exceed 10% of the limits?
In addition, if a new employee already has an exposure in
excess of 10% of the limits when they start work at the new
employer, must the new employer automatically monitor the
employee?
Answer: No. The licensee is only responsible for
evaluating the potential for exposure at its facility. If
the licensee makes an evaluation that the dose will not
exceed the 10% threshold, the licensee need not record or
monitor the dose. If the licensee opts to measure the
dose, although its preliminary evaluation shows that it is
not necessary and finds that the threshold has been
exceeded, it must reevaluate its program and provide
monitoring as required. In addition the licensee will need
to reconsider the requirements to sum internal and external
doses. (Reference: 10 CFR 20.1502)
