The following report was received via e-mail:
On November 17, 2014, the Agency [Texas Department of State Health] was notified by the licensee that a Troxler Model 3430, Gauge Serial No. 26893 containing a cesium-137 source, serial No. 750-92, activity - 0.30 GBq (8 mCi), and an americium-241 source, serial No. 47-23385, activity - 1.48 GBq (40 mCi), was damaged at a field site. The technician had placed the device at a sample location and extended the cesium source into the inspection hole. The technician then noticed a road grader driving directly at him so he ran out of the way and when he turned around the grader had run over the moisture density gauge. The licensee's RSO [Radiation Safety Officer] responded to the scene to inspect and recover the gauge. The device case was severely damaged, but the licensee was able to return the cesium source to the shielded position and secure it in position. The RSO verified the americium source was still in the device. The RSO took the damaged device to their facility for disposal. No individual received any significant additional exposure due to this event.
