10 CFR 20 Appendix C

Appendix C to Part 20-Quantities<a href="#N_1_20appc" id="ftn1" title="Footnote 1 hyperlink">¹</a> of Licensed Material Requiring Labeling <a href="#ftn1" name="N_1_20appc" title="Footnore 1">¹</a>The quantities listed above were derived by taking ¹/₁₀th of the most restrictive ALI listed in table 1, columns 1 and 2, of appendix B to §§ 20.1001-20.2401 of this part, rounding to the nearest factor of 10, and arbitrarily constraining the values listed between 0.001 and 1,000 µCi. Values of 100 µCi have been assigned for radionuclides having a radioactive half-life in excess of 10⁹ years (except rhenium, 1000 µCi) to take into account their low specific activity.
NOTE: For purposes of §§ 20.1902(e), 20.1905(a), and 20.2201(a) where there is involved a combination of radionuclides in known amounts, the limit for the combination should be derived as follows: determine, for each radionuclide in the combination, the ratio between the quantity present in the combination and the limit otherwise established for the specific radionuclide when not in combination. The sum of such ratios for all radionuclides in the combination may not exceed "1" (i.e., "unity").
