The gauge contains a 100 milliCurie (original activity) cesium-137 source. The shutter operates normally. The licensee reported the gauge will not present an exposure risk to any individual. The licensee stated it is in the process of trying to schedule repairs to the gauge. Additional information will be provided as it is received in accordance with SA 300. | ||

On June 30, 2020, the licensee reported that there had been another failure with the gauge. | On June 30, 2020, the licensee reported that there had been another failure with the gauge. The Radiation Safety Officer [RSO] was investigating to determine what had happened and learned that the rotary element and the source tube attached to it had come partially out of the gauge and when employees tried to put it back in it came apart into pieces. The two employees thought the source was still in the gauge housing and they picked up the pieces. They did not realize that one of the pieces they picked up was the source and it had separated from the source tube. One employee picked it up and gave it to the other employee who put it into his shirt pocket. The RSO contacted a licensed service company who put the source into a lead pig and it is now secured at the licensee's facility. The licensee is continuing to investigate, but initial dose calculations as of July 1, 2020 indicate the dose, especially to the one employee, will exceed reporting requirement of greater than 25 rem TEDE [Total Effective Dose Equivalent]. The licensee will conduct a re-enactment to collect better information for dose reconstruction and calculation. They have been given the information for REAC/TS and have indicated they will pursue contacting them for biodosimetry. Current activity for the Cesium-137 source is 95 milliCuries (was 100 milliCi original activity). More information will be provided as it is obtained in accordance with SA-300. | ||
