“The table 2 summation rule” means the sum of the quotient A/B where—

(a)

“A” means the quantity of each radionuclide listed in column 1 of Table 2 that is present in the substance or article; and

(b)

“B” means the quantity of that radionuclide specified in (as appropriate)—

(i)

column 2 of Table 2 where the substance or article is a solid or a relevant liquid;

(ii)

column 3 of Table 2 where the substance or article is any other liquid; or

(iii)

column 4 of Table 2 where the substance or article is a gas.
