1/ Values are given in Column I only for those materials normally used as gases.
2/ microcuries /g for solids
Note 1: Many radionuclides transform into other radionuclides. In expressing the concentrations in Appendix A, the activity stated is that of the parent radionuclide and takes into account the radioactive decay products.
Note 2: For purposes of s. DHS 157.09 (2) where there is involved a combination of radionuclides, the limit for the combination should be derived as follows: Determine for each radionuclide in the product the ratio between the radioactivity concentration present in the product and the exempt radioactivity concentration established in Appendix A for the specific radionuclide when not in combination. The sum of such ratios may not exceed "1".
Note 3: To convert microcuries-/ml to SI units of megabecquerels per liter multiply the above values by 37.
Example: Zirconium (40) Zr-97 (2x10-4 microcuries/ml multiplied by 37 is equivalent to 74 x 10"4 MBq/l). 2/ microcuries/g for solids.
