Utah Admin. Code R313-15-203 - Determination of External Dose from Airborne Radioactive Material
(1) Licensees or registrants shall, when
determining the dose from airborne radioactive material, include the
contribution to the deep dose equivalent, lens dose equivalent, and shallow
dose equivalent from external exposure to the radioactive cloud. See footnotes
1 and 2 of Appendix B of
10 CFR
20.1001 to 20.2402,(2010), which is
incorporated by reference.
(2)
Airborne radioactivity measurements and DAC values shall not be used as the
primary means to assess the deep dose equivalent when the airborne radioactive
material includes radionuclides other than noble gases or if the cloud of
airborne radioactive material is not relatively uniform. The determination of
the deep dose equivalent to an individual shall be based upon measurements
using instruments or individual monitoring devices.
