(b) for a substance that contains—

(i) only 1 of the radionuclides stated in schedule 1 , column 1—the concentration of the radionuclide is less than the amount worked out by multiplying the concentration stated in schedule 1 , column 2 shown opposite the radionuclide by 10; or

(ii) more than 1 of the radionuclides stated in schedule 1 , column 1—the substance’s disposal factor is not more than 1.

(3) In this section—

where—

"C" , for a radionuclide, means the radionuclide’s concentration, measured in Bq per gram.

"MC" , for a radionuclide, means the amount worked out by multiplying the concentration stated in schedule 1 , column 2 shown opposite the radionuclide by 10.
