On January 25, 2022, the NRC issued a Notice of Violation to KRONUS, Inc. (Licensee) for a severity level III violation for failure to survey, in accordance with 10 CFR 20.1501(a), those areas necessary for the licensee to comply with 10 CFR Part 20 regulations and evaluate potential radiological hazards. Specifically, between December 1999 and May 2021, the licensee failed to make adequate physical surveys with a radiation detection survey meter that could reasonably detect low activity amounts of iodine-125 contamination and did not perform surveys at the end of the day where unsealed iodine-125 was handled.
