N.H. Code Admin. R. He-P 4096.02 – Derivation of Combination Limits

(a) Where there is involved a combination of radionuclides, the limit for the combination shall be derived as follows:
1. (1) Determine the amount of each radionuclide possessed and 1,000 times the amount in Table 4096.1 for each of those radionuclides when not in combination; and
2. (2) The sum of the ratios of those quantities determined in He-P 4096.02(a) shall not exceed 1.

(b) To convert microcuries (mCi) to SI units of kilobecquerels (kBq), multiply the values determined in He-P 4096.02 by 37 kBq/mCi.
Example: Zirconium-97
10 mCi ×( 37 kBq/mCi) = 370 kBq
