Footnotes to Schedule C.
1. Values are given only for those materials
						normally used as gases.
2. [MICRO]Ci/gm
						for solids.
3. Numerical value expressed
						in "E notation" where the letter "E" represents "times ten raised to the power of,"
						thus, replacing the "x 10" in scientific notation, followed by the value of the
						exponent. (e.g. 1 x 102 = 1E2; 1 x
						10-2 = 1E-2)
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
___________________________
+
___________________________
[LESS
								  THAN EQUAL TO] 1
Exempt concentration of Isotope A
Exempt concentration of Isotope B
1. Amendment
						  filed 7-22-71; effective thirtieth day thereafter (Register 71, No.

2. Change without regulatory effect amending Arsenic and Beryllium
						  and adoption of NOTE filed 11-1-91 pursuant to section
						  100, title 1, California Code of
						  Regulations (Register 92, No. 5).
3. Amendment of listings for argon and
						  platinum and amendment of footnote 2 and NOTE filed 7-28-2006; operative 8-27-2006
						  (Register 2006, No. 30).
4. Repealer and new section filed 12-30-2014;
