| Title | Damaged Moisture Density Gauge |
| Event Description | The licensee's gauge operator was preparing to sample some work being done by a construction company when the company's road grader began backing into his sample area. The operator attempted to wave off the grader but he was in the grader operator's blind spot. The grader struck the gauge side and damaged the housing. The source rod was retracted so the sources were in their shielded position.
The RSO [Radiation Safety Officer] was contacted and performed an area survey and a survey on the gauge. There were no abnormal readings. The gauge was swipe tested and the licensee has sent the swipe off for analysis. No overexposures were reported. The gauge was a Troxler model 3440 which contained a 9 mCi Cs-137 source and a 44 mCi Am-241 source. The gauge is currently in secure storage at the licensee's facility. Once the swipe tests are analyzed, the disposition of the gauge will be determined. The site of the incident was Ann Arbor, MI. |
