Table 338.1 notes:

¹ to convert microcurie to kilobecquerels, multiply the microcurie value by 37;

² based on alpha disintegration rate of Th-232, Th-230 and their daughter products;

³ based on alpha disintegration rate of U-238, U-234 and U-235.

B. Note. Where a combination of isotopes in known amounts is involved, the limit for the combination shall 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 for the specific isotope when not in combination. The sum of such ratios for all the isotopes in the combination may not exceed "1" (i.e. "unity").
