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.
B. Notes.
(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) 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) 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) 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.
