*Based on alpha disintegration rate of Th-232, Th-230 and their daughter products.

**Based on alpha disintegration rate of U-238, U-234 and U-235.

NOTE: For purposes of Rules 224 to 231, where there is involved a combination of nuclides in known amounts, the limit for the combination should be derived as follows: Determine, for each nuclide in the combination, the ratio between the quantity present in the combination and the limit otherwise established for the specific nuclide when not in combination. The sum of such ratios for all the nuclides in the combination may not exceed "1" (i.e., "unity").
