Under Brown
University requirements:
Adults likely
to receive, in 1 year from sources external to the body, a dose in
excess of 10% of the limits in section 5.1 shall wear a dosimeter
during working hours.
Minors and declared
pregnant women likely to receive, in 1 year from sources external
to the body, a dose in excess of 10% of the limits in section 5.1
shall wear a dosimeter during work hours.
These dosimeters
shall be changed and processed each quarter. Records of the dose received
during the quarter shall be maintained by the Radiation Safety Office
and shall be sent annually to each authorized user. Requests for dosimetry
service for authorized users shall be addressed to the Radiation Safety
Office.
Persons who use
sources of radiation, except those who exclusively use low-energy
beta emitters such as Hydrogen-3, Carbon-14, Sulfur-35, and Phosphorus-33,
or use pure alpha emitters, may be required to wear dosimeters. Individuals
under 18 must wear a dosimeter if there is likelihood of a detectable
exposure. Anyone entering a high-radiation area (dose rate 100 mrem/hr)
must wear a self-reading dosimeter. Extremity dosimeters (ring badges)
must be worn if exposure to the hands and forearms greater than 10%
of the permissible limits is possible.
