of the need for an emergency plan is required if the sum of the ratios of the quantity of each radioactive material authorized to the quantity listed for that material in Schedule C exceeds one. 2 For Californium-252, the quantity may also be expressed as 20 milligrams. 3 Excludes Carbon-14 as carbon dioxide. 4 For uranium hexafluoride, the quantity is 50 kilograms in a single container or 1,000 kilograms total. 5 Waste packaged in Type B containers does not require an emergency plan.
