Any other radionuclide that is—103, or the quantity given in respect of that radionuclide in the Health Protection Agency’s publication “Exempt Concentrations and Quantities for Radionuclides not included in the European Basic Safety Standards Directive”(2).1, or the concentration given in respect of that radionuclide in the document referenced in column 2.
(a)

not of natural terrestrial cosmic origin; or

(b)

listed in Table 1 of schedule 8.

The summation rule in respect of column 2 of Table 2 is 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 radioactive material or radioactive waste; and

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

The summation rule in respect of column 3 of Table 2 is the sum of the quotients C/D where—

(a)“C” means the quantity of each radionuclide listed in column 1 of Table 2 that is present in the radioactive material or radioactive waste; and

(b)“D” means the quantity of that radionuclide specified in column 3 of Table 2.

+Parent radionuclides, and their progeny whose dose contributions are taken into account in the dose calculation (thus requiring only the exemption level of the parent radionuclide to be considered), are listed in the following:
