AGREEMENT STATE REPORT - CONTAMINATION EVENT

The following report was received by the North Carolina Division of Radiation Protection via email:

"On May 8, 2025, the licensee reported that a source [Am-241/Be, CPN23, 50mCi] was ruptured during a source recovery task. The source was being removed from a nuclear gauge down hole probe. Once the source was removed from the probe, it was immediately leak tested. Two leak tests were performed and both readings pegged at full scale on the licensee's GM Pancake Survey Meter. The area was immediately cleared and one individual (the person conducting the source removal) was found to have contamination on their hands at 6000 CPM and 3500 CPM on portions of their clothes. This person was immediately decontaminated and a follow-up urine bioassay revealed less than minimum detectable levels. No other employees were contaminated, and the source was secured, awaiting disposal via a radioactive waste broker. Additional surveys of the work area revealed areas that required decontamination. The area was secured from entry and is awaiting decontamination by an outside vendor."
