| Title | Agreement State Report - Damaged Moisture/Density Gauge |
| Event Description | The following report was received from the California Department of Public Health, Radiologic Health Branch (CA RHB) by email:
On August 30, 2017, the President and ARSO of Earth-Strata, Inc., contacted the CA RHB Brea office [at 1415 PDT] to report a moisture/density gauge had been run over by a bulldozer at a construction site in Santa Clarita, CA. The gauge is a CPN MC-3, S/N M36087027 (10 mCi Cs-137, 50 mCi Am:Be-241). [The licensee] stated that the gauge was on the ground with the Cs-137 source in the shielded position when it was struck by the bulldozer. The area around the gauge was isolated until the gauge operator was instructed by [the ARSO] to place the gauge in the transport case for transport to Maurer Technical Services to be inspected and to perform an emergency leak test. [The licensee] stated that the plastic cover of the gauge had been broken and the guide tube and source rod had broken off of the top of the source shield. [The licensee] stated that after the gauge was inspected by Maurer personnel, it was determined that the Cs-137 source remained in the shielded position and the Am:Be-241 source remained intact and was still attached to gauge. Maurer Technical Services will assist in the disposal of the gauge. The investigation will remain open and any citations will be deferred until the licensee provides the 30-day report. |
