AGREEMENT STATE REPORT - GAUGE SLIDING BLOCK FAILURE
The following is a summary of information provided by the South Carolina Department of Environmental Services (the Department) via phone and email:
The licensee notified the Department by telephone on April 29, 2026, that a Troxler Electronic Laboratories Model 3450 portable gauge (serial number 69119), containing an 8 millicurie Cs-137 sealed source and a 40 millicurie Am-241:Be sealed source, had a sliding block that failed to fully close.
During an internal safety audit on February 11, 2022, the licensee identified abnormal radiation levels from the gauge. The gauge was sent to the manufacturer in March 2022 for evaluation. The manufacturer's inspection report found the sliding block was approximately 25 percent open due to excessive dirt. The licensee reported that the gauge was repaired and maintained in March 2022.
This event was reported as a result of a recent Department inspection. The licensee did not report any overexposures or ongoing health or safety concerns. The Department's investigation is ongoing.
South Carolina Event Number: TBD
