NOTE: For purposes of 105 CMR 120.242(E), 120.245(A), and 120.281(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"-- that is, unity.

¹ The quantities listed above were derived by taking 1/10th of the most restrictive ALI listed in 105 CMR 120.296: Appendix B, Table I, Columns 1 and 2, rounding to the nearest factor of 10, and constraining the values listed between 0.001 and 1,000 microcuries (37 becquerels and 37 megabecquerels). Values of 100 microcuries (3.7 megabecquerels) have been assigned for radionuclides having a radioactive half-life in excess of 109 years, except rhenium, 1,000 microcuries (37 megabecquerels), to take into account their low specific activity.
