* To convert µCi to kB q, multiply the µCi value by 37.

** 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: Where tere is involved a combination of isotopes in known amounts, the limit for the combination should be derived as follows:

Determine, for each isotope in the combination, the ratio between the quantity present in the combination and the limit otherwise established forthe specific isotope when not in combination. The sum of such ratios for all the isotopes in the combination may not exceed "1" - that is, unity.
