Schedule 2

SECOND SCHEDULERegulations 4 (1) and (5), 27(10), 48(9), 50(4), 67(1) and First Schedule (Section A)Activity Limits And Material RestrictionsSection A –– Single RadionuclidesThe following basic values for single radionuclides of known identity, are given in Table 1 of this Schedule:

1. In the calculations of A1 and A2 for a radionuclide not in Table 1 of this Schedule, a single radioactive decay chain in which the radionuclides are present in their naturally occurring proportions and in which no daughter nuclide has a half-life either longer than 10 days or longer than that of the parent nuclide shall be considered as a single radionuclide, and the activity to be taken into account and the Al or A2 value to be applied shall be those corresponding to the parent nuclide of that chain. In the case of radioactive decay chains in which any daughter nuclide has a half-life either longer than 10 days or greater than that of the parent nuclide, the parent and such daughter nuclides shall be considered as mixtures of different nuclides.

2. For mixtures of radionuclides whose identities and respective activities are known the basic radionuclide values may be determined as follows:where, f(i) is the fraction of activity or activity concentration of radionuclide i in the mixture; X(i) is the appropriate value of A1 or A2, or the activity concentration for exempt material or the activity limit for an exempt consignment as appropriate for the radionuclide i; and Xm is the derived value of A1 or A2 or the activity concentration for exempt material or the activity limit for an exempt consignment in the case of a mixture.

3. When the identity of each radionuclide is known but the individual activities of some of the radionuclides are not known, the radionuclides may be grouped and the lowest radionuclide value, as appropriate, for the radionuclides in each group may be used in applying the formula in paragraph 2 of this section. Groups may be based on the total alpha activity and the total beta/gamma activity when these are known, using the lowest radionuclide values for the alpha emitters or beta/gamma emitters, respectively.

4. For individual radionuclides or for mixtures of radionuclides for which relevant data are not available, the values shown in Table 2 of this Schedule shall be used.<caption>TABLE 1 –– BASIC
