Naturally Occurring Radioactive Materials or Accelerator-Produced Radioactive Materials (NARM)
Naturally Occurring Radioactive Materials or Accelerator-Produced Radioactive Materials (NARM) : Radioactive materials not covered under the AEA that are naturally occurring or produced by an accelerator. Accelerators are used in sub-atomic particle physics research. These materials have been traditionally regulated by States. A subset of NARM is NORM. NARM waste with more than 2 nCi/g of 226Ra or equivalent is commonly referred to as discrete NARM waste; below this threshold, the waste is referred to as diffuse NARM waste. NARM waste is not covered under the AEA, not a form of LLW, and is not regulated by NRC.
