During an inventory for license transfer, a Delphi Instruments electron capture device, model #4402 S/N 2546, containing 50 mCi
Tritium was discovered missing. The device was used to measure contamination in
argon gas streams. The licensee received the device at their NY facility in April 2000. Since no wipe test is required the last use of this device is unknown. The licensee conducted two exhaustive searches with negative results.
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.
