Beta and/or gamma emitting radioactive material not
								listed above with half-life less than three years
1X10-10
1X10-6
NOTE 1: Many radioisotopes disintegrate 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.
____________________________________
1/ Values are given in Column I only for those materials
				  normally used as gases
2/ µCi/gm are for solids
NOTE 2: For purposes of Section 303 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
				  concentration present in the product and the exempt concentration established
				  in Schedule A for the specific isotope when not in combination. The sum of such
				  ratios may not exceed "1" (i.e. unity).
