On March 31, 2023, the NRC issued a notice of violation (Notice) to Radiation Safety Services (licensee) for one Severity Level (SL) III violation. This violation is related to an NRC investigation conducted to determine whether employees of Radiation Safety Services, LLC, while working under reciprocity in NRC jurisdiction, willfully transferred byproduct material to an NRC licensee without verifying that it was authorized to receive and possess the material. The violation involved the licensee’s transfer of byproduct material to a company that was not specifically licensed by the NRC to receive the material, contrary to requirements of Title 10 of the Code of Federal Regulations (10 CFR) 150.20(b)(3). The NRC considers this to be a significant violation because the transfer of licensed radioactive material to an unauthorized entity provides greater opportunities for misuse or mishandling of the radioactive material. Therefore, this violation has been categorized in accordance with the NRC Enforcement Policy at Severity Level III.
