The NRC's task is to oversee the safe use of nuclear energy and its radioactive by‐products. The definition of by‐product materials was expanded in 2005 by amendments to the original Atomic Energy Act of 1954. To this end, it regulates the production, possession, and use of the following:

 Source materials. Uranium and thorium, and their ores containing at least 0.05% U or Th.

 Special nuclear material (SNM). Plutonium, 233U, and uranium enriched in 233U or 235U.

 Any material, except SNM, produced or made radioactive incident to making or using SNM.

 Radium sources.

 Material made radioactive in a particle accelerator.

 Sources of naturally occurring radioactive material.
