North Carolina Department of Health and Human Services, Division of Health Service Regulation, Radioactive Materials Branch (the Department) via email:
The licensee reported that around 1600 EDT on September 4, 2024, their portable nuclear gauge (PNG) was run over by another vehicle at a construction site. The PNG is a Troxler 3440 (serial number 25787), containing 8 millicuries of Cs-137 (serial number 20-2119) and 40 millicuries of Am-241/Be (serial number 41-9543). The licensee dispatched their recovery team immediately. They were able to retract the source rod back into the PNG with the source block closed. Readings taken around the gauge indicated no readings in excess of transportation index requirements. Additional surveys of the work area indicated the source was intact and in the safe position. The PNG was then transported to the manufacturer for repair.
The Department's investigation is ongoing and this report will be followed up on to close and complete the record.
