1The quantities listed above
					 were derived by taking 1/10 of the most restrictive ALI listed in table 1,
					 columns 1 and 2 of 10 CFR Part 20, Appendix B, rounding to the nearest factor
					 of 10, and arbitrarily constraining the values listed between 0.001 and 1,000
					 [MICRO]Ci. Values of 100 [MICRO]Ci have been assigned for radionuclides having
					 a radioactive half-life in excess of 109 years
					 (except rhenium, 1000 [MICRO]Ci) to take into account their low specific
					 activity.
NOTE: For purposes of
					 10 CFR
					 20.1902(e),
					 10 CFR
					 20.1905(a), and
					 10 CFR
					 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").
