Alabama Radiation Control (the agency) via email:
Licensee advised that a Troxler 3430 serial number 79905, nominally with 8 mCi of cesium-137 and 40 mCi of americium241/beryllium, was lost leaving a job site in north Alabama. The licensee stated that the gauge fell from the technician's truck. The gauge has not been located as of this reporting.
The agency received information about this matter the evening of 1/10/23 and the morning of 1/11/2023.
Alabama Radiation Control will provide more information as the investigation continues.
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.
