* Values are given in Column 1 only for those materials
						normally used as gases.
* * µCi/gm for solids.
NOTE 1: Many radionuclides disintegrate into nuclides
						which are also radioactive. In expressing the concentrations in Schedule A the
						activity stated is that of the parent nuclide and takes into account the
						daughters.
NOTE 2: For purposes of Rule 65 where there is involved a
						combination of nuclides, the limit for the combination should be derived as
						follows: Determine for each nuclide in the product the ratio between the
						concentration present in the product and the exempt concentration established
						in Schedule A for the specific nuclide when not in combination. The sum of such
						ratios may not exceed "1" (i.e., unity).
