Current through Register Vol. 64, No. 1, January 1, 2025

Section 333-120-0120 - Determination of External Dose from Airborne Radioactive Material

Licensees must, 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 ( 10 CFR, Part 20, Appendix B, Footnotes 1 and 2 to 20.1001 to 20.2401).

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.
