| ENS 56979 | 16 February 2024 22:43:00 | Agreement State | Damaged Troxler Gauge | The following was received from the the Virginia Office of Radiological Health, Radioactive Materials Program via email: At approximately 1743 EST, on 2/16/2024, the Virginia Office of Radiological Health was notified of an incident involving a portable nuclear gauge. At approximately 1600 EST, a Troxler gauge; Model 3430, containing 8 mCi of Cs-137 and 40 mCi of Am-241:Be, was struck by a dump truck on a building construction site located in Chester, VA. The authorized user notified the radiation safety officer (RSO) who arrived on site and then he notified the Virginia Emergency Management's Operations Center at approximately 1630 EST. Per the RSO, the gauge was sitting on soil with the source in the retracted, shielded position when it was run over by a dump truck. The source remained in the shielded position, but the handle was bent slightly. He did not attempt to turn it on or extend the rod for any reason. He obtained survey readings of 2.5 mR/h at 12 inches and 0.1 mR/h at 3 feet from the gauge. The gauge was placed in its transportation box, secured in the back of a pickup truck, and transported back to the licensee's office for secure storage. The gauge will be sent to the manufacturer for assessment. The Radioactive Materials Program will follow up with an investigation. Virginia Report Number: VA240002 |
