   Table 329.1 notes:

   ¹ values are given in column I only for those materials normally used as gases;

   ² microcuries per gram for solids.

2. B. Notes.

   1. (1) Many radioisotopes disintegrate into isotopes which are also radioactive. In expressing the concentrations in Subsection A the activity stated is that of the parent isotope and takes into account the daughters.
   2. (2) For purposes of 20.3.3.302 NMAC where there is involved a combination of isotopes, the limit for the combination shall 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 Subsection A of this section 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) / (exempt concentration of isotope A) + (concentration of isotope B in product) / (exempt concentration of isotope B) <1.
   3. (3) The values in this table are presented in scientific notation. In this notation, a value of 3 x 10^-4 represents a value of 3E-4 or 0.0003.
   4. (4) To convert microcuries to SI units of kilobecquerels multiply the above values by 37. For example: Zirconium-97 of 2x10^-4 microcurie multiplied by 37 is equivalent to 0.0074 kilobecquerel or 7.4 becquerels.
