NOTE: In any case where there is a mixture in waste of more than one radionuclide, the limiting values for purposes of this paragraph shall 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 this paragraph 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" (i.e., "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 CLc respectively, then the concentrations shall be limited so that the following relationship exists:

(Ca/CLa) + (Cb/CLb) + (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/ALa) + (Ab/ALb) + (Ac/ALc) < 1
