The following was received from the
Arizona Department of Health Services (Department) via email:
The Department received notification from the licensee that a portable gauge was lost. A technician left the portable gauge on the tailgate of his truck while completing paperwork and then drove off. When he realized that the gauge was missing, he retraced his steps but was unable to locate it. The gauge is a Troxler 3430, Serial Number 32909, containing approximately 8 milliCuries of Cesium-137 and 40 milliCuries of Americium-241:Beryllium. The Department has requested additional information and continues to investigate the event.
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.
