Note: |
For purposes of WAC 246-221-120(8), 246-221-130(7)(a), and 246-221-240(1) where there is involved a combination of radionuclides in known amounts, the limit for the combination shall be derived as follows: Determine, for each radionuclide in the combination, the ratio between the quantity present in the combination and the limit otherwise established for the specific radionuclide when not in combination. The sum of such ratios for all radionuclides in the combination may not exceed "1" -- that is, unity. |

The quantities listed above were derived by taking 1/10th of the most restrictive ALI listed in Table I, Columns 1 and 2, of WAC 246-221-290, rounding to the nearest factor of 10, and constraining the values listed between 37 Bq and 37 MBq (0.001 and 1,000MICROCi). Values of 3.7 MBq (100 MICROCi) have been assigned for radionuclides having a radioactive half-life in excess of E+9 years, except rhenium, 37 MBq (1,000 MICROCi), to take into account their low specific activity. |
|
* |
To convert MICROCi to kBq, multiply the MICROCi value by 37. |
