| 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.
