Greater than class C LLWs wastes include trash that should be buried deep in the ground

Greater than class C LLWs wastes include trash that should be buried deep in the ground. Examples of such wastes include transuranic whose half-lives exceed five years, and their radioactivity is more than 100nCi/g. The NRC does not cover NORM/NARM wastes, which fall into two classes namely diffuse and discrete NORM/NARM. Diffuse NORM/NARM have activities less than 2nCi/g ^226 Ra while discrete NORM/NARMs have activities greater than 2nCi/g ²²⁶ Ra.
