1/Values are given in Column I
				  only for those materials normally used as gases.
2/µCi/g are for
				  solids.
NOTE 1: Many radioisotopes transform into isotopes which are
				  also radioactive. In expressing the concentrations in Schedule A, the activity
				  stated is that of the parent isotope and takes into account the
				  daughters.
NOTE 2: For purposes of
				  410 IAC
				  5-3-4 where there is involved a combination of
				  isotopes, the limit for the combination should be derived as follows: Determine
				  for each isotope in the product the ratio between the radioactivity
				  concentration present in the product and the exempt radioactivity concentration
				  established in Schedule A for the specific isotope when not in combination. The
				  sum of such ratios may not exceed "1".
