or that concentration which gives rise to a dose to a member of the public of 10 microsieverts per year calculated by reference to guidance by Euratom in RP 122 part 1.

4.  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.

References in Table 1 and Table 2 to + and secE+W+S

5.  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.
