NOTE 1:  Many radionuclides transform into nuclides that are also radioactive.  In expressing the concentrations in this Appendix, the activity stated is that of the parent radionuclide and takes into account the daughters. NOTE 2:  For purposes of Section 330.40 where there is involved a combination of radionuclides, the limit for the combination should be derived as follows:  Determine for each radionuclide in the product the ratio between the radioactivity concentration present in the product and the exempt radioactivity concentration established in this Appendix for the radionuclide when not in combination.  The sum of such ratios may not exceed "1". EXAMPLE: Concentration of Nuclide A in Product + Concentration of Nuclide B in Product ≤ 1 Exempt Concentration of Nuclide A Exempt Concentration of Nuclide B
