In any case where there is a mixture in waste of more than one radionuclide, the limiting values for purposes of this Appendix must be determined as follows:
For each radionuclide in the mixture, calculate the ratio between the quantity present in the mixture and the limit established in Appendix 004-G for the specific radionuclide when not in a mixture. The sum of such ratios for all the radionuclides in the mixture may not exceed "1" or "unity".
Examples: If radionuclides a, b, and c are present in concentrations Ca, Cb, and Cc, and if the applicable concentrations are CLa, CLb, and CL c respectively, then the concentrations shall be limited so that the following relationship exists:
(Ca/CLa ) + (C b/CL b ) + (Cc/CLc) < 1
If the total curies for radionuclides a, b, and c are represented Aa, Ab, and Ac, and the annual curie limit for each radionuclide is ALa, ALb, and ALc, then the generator is limited to the following:
(Aa/AL a) + (Ab/AL=) + (A c/ALc) < 1
