When a combination of nuclides is involved, the limit for the combination shall be derived as follows: For each nuclide, the licensee shall determine the ratio between the quantity authorized on the license and the quantity established in this Appendix A for the form of the material (sealed source or unsealed material). If the sum of the ratios for all nuclides is greater than one, then the licensee shall post financial assurance arrangements.
