Abstract:
An Office of Investigation (OI) investigation by the U.S. Nuclear Regulatory Commission (NRC) determined that, on three separate occasions over the past 10 years, technologists in one licensed nuclear medicine program were injected with radiopharmaceuticals without Authorized User knowledge or approval. The most recent instance, the one that precipitated the investigation, was discovered by the licensee and self-reported to the NRC; the other two instances were discovered during the OI investigation and came as a complete surprise to the licensee. In a mediated Alternative Dispute Resolution (ADR) involving the licensee, a professional, independent mediator and representatives of the NRC, an agreement was worked out whereby the licensee would admit to the violations and work with the NRC to inform other licensees that this is not an acceptable practice and that there are additional precautions that licensees can and should take to assure that such violations do not happen on their watch.
