Any material that has been made radioactive by use of a particle accelerator and is produced, extracted, or converted after extraction for use for a commercial, medical, or research activity; and e. Any discrete source of naturally occurring radioactive material (NORM), other than source material that the Nuclear Regulatory Commission (NRC), in consultation with the Administrator of the Environmental Protection Agency, the Secretary of Energy, the Secretary of Homeland Security, and the head of any other appropriate federal agency, determines would pose a threat similar to the threat posed by a discrete source of radium-226 to the public health and safety or the common defense and security, that is extracted, or converted after extraction, for use for a commercial, medical, or research activity.
2. “General license” means a license effective under regulations promulgated by the Board without the filing of an application with the Department or the issuance of licensing documents to particular persons to transfer, acquire, own, possess, or use quantities of, or devices or equipment utilizing, radioactive material.
