Any other radionuclide that is:103, or the quantity given in respect of that radionuclide in the [F1Public Health England] publication ‘Exempt Concentrations and Quantities for Radionuclides not Included in the European Basic Safety Standards DirectiveM1.1, or the concentration given in respect of that radionuclide in the publication referenced in column 2.
(a) not of natural terrestrial or cosmic origin, or
(b) listed in Table 2 in this Schedule.

(2) The summation rule in respect of column 2 of Table 5 is the sum of the quotients A/B where—

(a)A” means the quantity of each radionuclide listed in column 1 of Table 5 that is present in the material and waste, and

(b)B” means the quantity of that radionuclide specified in column 2 of Table 5.

(3) The summation rule in respect of [F2column 3] of Table 5 is the sum of the quotients C/D where—

(a)C” means the concentration of each radionuclide listed in column 1 of Table 5 that is present in the material and waste, and

(b)D” means the concentration of that radionuclide specified in column 3 of Table 5.
