AGREEMENT STATE REPORT - LOST AND FOUND DEVICE | |||

On September 15, 2020, at 1700 CDT, the Agency was notified by the licensee's radiation safety officer (RSO) that one of their technicians had left a Troxler model 4640B density gauges at a job site overnight. The technician had completed their work on September 14, 2020, and left the job site after completing their paperwork, but failed to store the device into their truck. The RSO stated the gauge handle was locked and did not believe any individual would receive an exposure. The RSO stated the device contains two cesium-137 sources, but did not know the activities. The manufacturer's website states the activity to be 8 (+ or - 1) milliCuries. The licensee's license states a device source cannot exceed 9 milliCuries. The RSO stated they had technicians out searching for the gauge. At 1736 CDT, on September 15, 2020, the RSO contacted the Agency and reported the gauge had been recovered. He could not provide any additional information. Additional information has been requested. If during the investigation of this event it is determined that an individual could have been exposed, the Agency will submit an update to this report. Additional information will be provided as it is received in accordance with SA-300. | On September 15, 2020, at 1700 CDT, the Agency was notified by the licensee's radiation safety officer (RSO) that one of their technicians had left a Troxler model 4640B density gauges at a job site overnight.

On October 7, 2020, the Agency was notified by the licensee that the gauge only had one source and not two as first reported. The licensee stated it thought it had two sources because of the way it calculates the density of the top two inches. The licensee stated it has only one source, but two detectors so it can calculate thin lift density. Additional information will be provided as it is received in accordance with SA-300. | On October 7, 2020, the Agency was notified by the licensee that the gauge only had one source and not two as first reported.

Sources that are "Less than IAEA Category 3 sources," are either sources that are very unlikely to cause permanent injury to individuals or contain a very small amount of radioactive material that would not cause any permanent injury. Some of these sources, such as moisture density gauges or thickness gauges that are Category 4, the amount of unshielded radioactive material, if not safely managed or securely protected, could possibly - although it is unlikely - temporarily injure someone who handled it or were otherwise in contact with it, or who were close to it for a period of many weeks.
