EN Revision Text: AGREEMENT STATE REPORT - DAMAGED MOISTURE DENSITY GAUGE
The following was received from the Texas Department of State Health Services (the Agency) via email:
"On September 17, 2021, the Agency was notified by the licensee that a Troxler 3411 moisture density gauge containing a 40 milliCurie americium - 241 source and an 8 milliCurie cesium - 137 source was damaged at a temporary job site. The licensee reported that while the gauge was sitting on the ground and not being used it was run over by a bulldozer, snapping the operating arm of the cesium source. The source was in the shielded position when the event occurred and a radiation survey of the gauge after the event verified it was still fully shielded. The licensee stated the gauge would be returned to its storage location and arrangements would be made to have the gauge disposed of. No individual received an exposure that exceeded any limit. Additional information will be provided as it is received in accordance with SA-300."
Texas Incident No.: 9885
* * * UPDATE FROM ART TUCKER TO THOMAS HERRITY AT 11:23 ON 09/20/21 * * *
The following information was received via e-mail:
"Received pictures of the gauge. Pictures show the rod for the cesium source was bent. The dose rate meter appears to be reading 0.8 millirem per hour."
