On March 22, 2021, the Agency was notified by the licensee's radiation safety officer (RSO) that earlier that day the shutter on a Berthold LD 8010 containing a 20 millicurie cesium-137 (original activity) source had failed to close. The gauge is installed on an inline section of pipe used in well fracking. The RSO stated that the roll pin for the shutter had failed and the operating arm would not rotate the shutter. The gauge was removed from the pipe and the operator was able to close the shutter. The RSO stated no overexposures occurred due to the event. The RSO stated a radiation survey of the gauge indicated dose rates were normal. The gauge was secured in a trailer on-site. The RSO stated the manufacturer was contacted and gauge will be packaged in a type 'A' container and sent to the manufacturer for repair. Additional information will be provided as it is received in accordance with SA-300.
