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.
