| Title | Troxler Moisture Density Gauge Damaged by Paving Equipment |
| Event Description | While preparing to conduct a measurement, the gauge operator placed the gauge on the asphalt. A paving roller operator did not see the gauge and ran it over.
At the time of the accident, the source was in its shielded and locked position. While the case and controls of the gauge were damaged, there was no damage to the source or the shield. As a precaution, the Radiation Safety Officer contacted the local hazmat team to confirm the source was not damaged. A leak check swipe was performed by the gauge owner and it was sent to Troxler for evaluation. There were no overexposures to the workers or members of the public. The gauge is a Troxler model 3430 (serial number 37669). It contains a 9 mCi Cs-137 source (serial number 77-4904) and a 44 mCi AmBe source (serial number 78-2427). The gauge will be returned to Troxler for disposal.
The licensee also reported the event to the New Jersey Department of Environmental Protection (NJDEP) at 1630 EST on 12/9/16. Additional information included: The license reported the gauge user was nearby, but not in direct observation of the device, at the time of the incident. NJDEP will be investigating further. The incident is reportable within 24-hours under N.J.A.C. 7:28-51.1 (10 CFR 30.50(b)2). NJDEP is tracking this incident internally as incident ID# C62454. NMED Report No. to be assigned. Notified R1DO (Schroeder) and NMSS_EVENTS_NOTIFICATION Resource, both via email. |
