| Title | Damaged Moisture Density Gauge |
| Event Description | While performing measurements at a construction site in Big Rapids, MI, a Troxler Model 3430 was struck by a bulldozer while the source rod was extended. While attempting to retract the source, the 9 mCi Cs-137 source disconnected from the source rod. The RSO covered the source and established boundaries around the source.
The licensee contacted the NRC Operations Center to get authorization to transport the source back to their storage facility. Notified R3DO (Reimer) and R3DNMS (McCraw) and placed them on a conference call with the licensee. The licensee was authorized to transport the source, in a sand-filled bucket, back to their facility. The Troxler serial number is 23659 and also contained a 44 mCi AmBe source. The AmBe source is in the shield. |
