The following report was received by the
California Department of Public Health , Radiation Health Branch (
RHB) via email:
CTE CAL, Inc. radiation safety officer (RSO) contacted RHB by email at 1634 [PDT] on March 20, 2024. A portable moisture density gauge containing radioactive material (Troxler Model 3430, Serial #T343 23828, Cs-137/Am-241:Be, 8mCi/40mCi) was run over by a smooth drum roller, on a construction site. The source rod and handle were damaged, and the source end of the rod broke off and was still on the ground. The accident site was cordoned off with barrier tape and the broken source rod and Cs-137 source were recovered by Pacific Nuclear Technology (PNT) and placed into a shielded recovery drum. The accident site was surveyed and no radiation above background was found. The damaged gauge and recovery drum were transported to PNT to be surveyed for radiation leakage. PNT surveyed the gauge, leak tested the sources, and determined that the sources were still intact and there was no leakage of radioactive material.
RHB will continue to investigate the circumstances surrounding the accident.
