Current through Register Vol. 46, No. 39, September 25, 2024
(a)
External radiation sources. Each person who possesses any radiation source
shall supply and require the proper use of appropriate, calibrated and operable
individual monitoring devices by:
(1) adults
likely to receive, in one year from sources external to the body, a dose in
excess of 10 percent of the limits in section
16.6(a)(1)
of this Part; and
(2) minors and
declared pregnant women likely to receive, in one year from sources external to
the body, a dose in excess of 10 percent of any of the applicable limits in
section
16.6(g)
or
16.6(h)
of this Part; and
(3) individuals
entering a high or very high radiation area.
(b) A person supplying personnel monitoring
devices to individuals as required by subdivision (a) of this section shall
ensure that the individuals wear such devices as follows:
(1) An individual monitoring device used for
monitoring the dose to the whole body shall be worn at the unshielded location
of the whole body likely to receive the highest exposure.
(2) An individual monitoring device used for
monitoring the dose to an embryo/fetus of a declared pregnant woman, pursuant
to section
16.6(h)(1)
of this Part, shall be located at the waist under any protective apron worn by
the woman.
(3) An individual
monitoring device used for monitoring the eye dose equivalent shall be located
at the neck outside any protective apron worn by the individual, or at an
unshielded location closer to the eye.
(4) An individual monitoring device used for
monitoring the dose to the extremities shall be worn on the extremity likely to
receive the highest exposure. The device shall be oriented to measure the
highest dose to the extremity being monitored.
(c) All personnel monitoring devices, except
for direct and indirect reading dosimeter and those dosimeters used to measure
the dose to any extremity, that require processing to determine the radiation
dose and which are supplied pursuant to subdivision (a) of this section, or
with conditions specified in a license or registration shall be processed and
evaluated by a dosimetry processor:
(1)
holding current personnel dosimetry accreditation from the National Voluntary
Laboratory Accreditation Program (NVLAP) of the National Institute of Standards
and Technology; and
(2) approved in
this accreditation process for the type of radiation or radiations included in
the NVLAP program that most closely approximate the type of radiation or
radiations for which the individual wearing the dosimeter is
monitored.
(d) Intake of
radioactive material. Each licensee shall perform all appropriate measurements
of those specified in section
16.6(d)(1)
of this Part which will enable him/ her to determine the occupational intake of
radioactive material by and assess the committed effective dose equivalent to:
(1) adults likely to receive, in one year, an
intake in excess of 10 percent of the applicable ALI in Appendix 16-C, Table 1,
Columns 1 and 2, infra; and
(2)
minors and declared pregnant women likely to receive, in one year, a committed
effective dose equivalent in excess of 0.50 mSv (0.05 rem).
