Note: For purposes of
					 12VAC5-481-930,
					 where there is involved a combination of isotopes in known amounts, the limit
					 for the combination should be derived as follows: Determine, for each isotope
					 in the combination, the ratio between the quantity present in the combination
					 and the limit otherwise established for the specific isotope when not in
					 combination. The sum of such ratios for all the isotopes in the combination may
					 not exceed "1" (i.e., "unity").
