Footnotes to Schedule C.
Note: 1: Many radioisotopes disintegrate into isotopes which are also radioactive. In expressing the concentrations in Schedule C, the activity stated is that of the parent isotope and takes into account the daughters.
Note: 2: 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 C for the specific isotope when not in combination. The sum of such ratios may not exceed “1” (i.e., unity).
Example:
Concentration of Isotope A in Product | Concentrate of Isotope B in Product | ||
+ | ≤ 1 | ||
Exempt concentration of Isotope A | Exempt concentration of Isotope B |
