1The quantities listed above were derived by taking 1/10th of the most restrictive annual limit on intake (ALI) listed in Table I, Columns 1 and 2, of Appendix 004-B to Section 004, rounding to the nearest factor of 10, and constraining the values listed between 37 Bq and 37 MBq (0.001 and 1,000 µCi). Values of 3.7 MBq (100 µCi) have been assigned for radionuclides having a radioactive half-life in excess of 109 years, except rhenium, 37 MBq (1,000 µCi), to take into account their low specific activity. | NOTE: For purposes of 180 NAC 4-34.05, 4-037.01 and 4-057.01 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" or unity. | ||
