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”[^f01001].	1, or the concentration given in respect of that radionuclide in the document referenced in column 2.
not of natural terrestrial cosmic origin; or listed in Table 1 of schedule 8.	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”[^f01001].	1, or the concentration given in respect of that radionuclide in the document referenced in column 2.

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.
