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.
AGENCY NOTE: Possession of special nuclear material
				  (Plutonium, Uranium-233 and Uranium-235) is limited to quantities not
				  sufficient to form a critical mass as defined in 32 Ill. Adm. Code
				  310.20.
