Any other solid or relevant liquid radionuclide that is not of natural terrestrial or cosmic origin	or that concentration which gives rise to a dose to a member of the public of 10 microsieverts per year calculated by reference to the International Atomic Energy Agency publication “Application of the Concepts of Exclusion, Exemption and Clearance”, IAEA Safety Standards Series No. RS-G-1.7.]

(2) The Table 2 column 2 summation rule means the sum of the quotients A/B where—

(a)“A” means the concentration of each radionuclide listed in column 1 of Table 2 that is present in the substance or article, and

(b)“B” means the concentration of that radionuclide specified in column 2 of Table 2.

3. Where any radionuclide carries the suffix “+” or “sec” in Table 1 or Table 2—

(a)that radionuclide represents the parent radionuclide in secular equilibrium with the corresponding daughter radionuclides which are identified in column 2 of Table 3 in respect of that parent radionuclide, and

(b)a concentration value given in a table in this Part in respect of such a parent radionuclide is the value for the parent radionuclide alone, but already takes into account the daughter radionuclides present.
