Any other radionuclide that is:	103, or the quantity given in respect of that radionuclide in the [F1 Public Health England] publication ‘Exempt Concentrations and Quantities for Radionuclides not Included in the European Basic Safety Standards Directive’M1 .	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 [F2 column 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.
