In determining the dose from airborne radioactive material, the licensee shall include the contribution to the deep-dose equivalent, lens-dose equivalent, and shallow-dose equivalent from external exposure to the radioactive cloud (see Schedule RHS 8-30 footnotes 1 and 2).
(Note: Airborne radioactivity measurements and DAC values should 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 should be based upon measurements using instruments or individual monitoring devices.)
1 An organ or tissue is considered significantly irradiated if the product of the weighting factors, W T , and the committed dose equivalent, H T50 , per unit intake for that organ or tissue is greater than 10 percent of the maximum weighted value of H T50 (i.e., W T H T50 ) per unit intake for any organ or tissue.
