| Title | Troxler Moisture Density Gauge Inadvertently Bumped by Truck |
| Event Description | The following summary information was provided by the licensee via telephone:
On 7/31/2023 at about 0730 MDT, employees of the City of Great Falls were standardizing a Troxler moisture density gauge (contained 9 millicuries of cesium-137 and 44 millicuries of americium-241) with the gauge on an asphalt lot and the source in its cage; as per standard practice. A loader truck inadvertently hit the gauge but was halted before it ran over the gauge. Some plastic on the gauge was damaged. The licensee halted operations and restricted access. Subsequently, radiation levels of 0.294 millirem per hour at 1 foot and 0.004 millirem per hour at 4 feet were measured, which were essentially background levels. No overexposure or other personnel injury were reported. |
