The following was report received from the state of
Texas via email:
On December 30, 2020, the licensee reported that during an in-depth audit it had been unable to locate two ThermoFisher model 5192 densitometers, each containing 200 milliCuries of cesium-137. The licensee had records showing it possessed them at one of its facilities more than two years ago, but it could neither physically locate them nor find any records showing their disposition. The licensee has continued its investigation but still has not determined the location or disposition of the devices. Serial Numbers for the two devices are B7713 and B7850. More information will be provided as it is obtained in accordance with SA-300.
Texas Incident # I-9831.
THIS MATERIAL EVENT CONTAINS A "LESS THAN CAT 3" LEVEL OF RADIOACTIVE MATERIAL
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.
