QUANTITIES OF LICENSED MATERIAL REQUIRING LABELING

Subpart 1. Explanation. The quantities listed in subpart 3 were derived by taking one-tenth of the most restrictive ALI listed in part 4731.2750 , subpart 7, Table 1, columns 1 and 2, rounding to the nearest factor of ten, 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 10 9 years (except rhenium, 1,000 µCi) to take into account their low specific activity. Subp. 2. Combination of radionuclides. For purposes of parts 4731.2310 , subpart 5; 4731.2340 , item A; and 4731.2600 , subpart 1, 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 one. Subp. 3. Quantities requiring labeling. The following quantities of licensed material require labeling: Radionuclide Abbreviation Quantity (µCi) Hydrogen-3 H-3 1,000 Beryllium-7 Be-7 1,000 Beryllium-10 Be-10 1 Carbon-11 C-11 1,000 Carbon-14
