Radioactive Materials

1.
The value for any alpha emitting nuclide not listed above and for mixtures of unknown alpha emitters is 10 Ci [see
835, Appendix E].
2.
The value for any non-alpha emitting nuclide and for mixtures of these nuclides of unknown composition is 100
Ci [see 835, Appendix E].
3.
When the radioactive material consists of a mixture of known quantities of listed nuclides, determine the value by
summing the fractions of the quantity of each radionuclide divided by the accountability value for that nuclide. If
the sum of the fractions exceeds unity (1), the value has been exceeded [see 835, Appendix E].
