AGREEMENT STATE REPORT - LOST GAUGE
The following report was received by the California Department of Public Health:
"On March 15, 2024, the RSO [radiation safety officer] for RMA Group notified the California's Department of Public Health, Radiologic Health Branch of the loss of a Troxler moisture density gauge. The serial number is 30520, and it contains 8 mCi of Cs-137 and 40 mCi of Am-241/Be. The Troxler gauge was inside a locked type A transit case and the trigger lock was used to secure the Cs-137 rod into the safe position. The gauge was reported as lost from the back of the operator's open bed pick-up truck. The Radiologic Health Branch is conducting an investigation of 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.
