Question 445: In this example, it has been determined that
an individual is not likely to exceed 5 rems shallow dose
equivalent from any sources with the possible exception of
dose from hot particles. There is a potential that
exposure to an individual from a hot particle may occur and
that the dose to the individual from a hot particle, should
it occur, may potentially exceed 5 rems shallow dose
equivalent. In this circumstance, may the potential dose
resulting from a potential exposure to a hot particle be
disregarded for the purpose of the evaluation on the basis
that the dose is not likely to exceed 10% of the applicable
limit? Note that the scope of this question is limited to
the requirements for individual monitoring (�.1502) and
is not intended to address the general requirements for
radiological surveys (�.1501).
Answer: Yes. The fact that an individual has the
potential to receive a dose does not mean that the
individual is likely to receive the dose. [Note: It should
also be recognized that individual monitoring devices
(personal dosimeters) are not appropriate for measuring
doses from hot particles on or near the skin.] (Reference:
10 CFR 20.1502).
