§ 3. In the case of natural uranium and natural thorium, the limits are set at 1 . 10-4 and 1 . 10-6 curies respectively.

By custom one curie of natural uranium corresponds to:

3 77 . 1010 dis/sec of U238,

3 77 . 1010 dis/sec of U234 and

1 77 . 109 dis/sec of U235.

3 77 . 1010 dis/sec of Th232 and

3 77 . 1010 dis/sec of Th228.

§ 4. In the case of the radioactive nuclides Nd144, Sm147, Rb87, In115, Re187, the requirements for reporting and obtaining prior authorisation may be waived, irrespective of the quantities used.

§ 5. In the case of a mixture of radioactive nuclides of differing radiotoxicity, the radiotoxicity of the mixture is determined as follows : the ratio is calculated for each component radionuclide in the mixture, between the quantity present expressed in curies and the limit laid down in the Radiotoxicity Table in §§ 1 and 2 for the nuclide concerned. The sum of these ratios for all the nuclides in the mixture may not exceed 1.

§ 6. Radionuclides not shown in the radiotoxicity groups in § 2 and the radiotoxicity of which is uncertain or unknown must be considered to belong to the highest radiotoxicity category.
