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 § 30.14 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).Example:
