| ENS 55159 | 26 March 2021 15:13:00 | Agreement State | Gauge Abandoned on Side of Road | The following report is from the California Department of Public Health, Radiation Health Branch (CDPH-RHB): CDPH-RHB forwarded a March 26, 2021, 0813 (PDT) email from a Sacramento County Environmental Specialist. The message stated that a moisture density gauge had been found alongside Jackson Highway in Sacramento the previous night and was being stored at the Caltrans yard in Sacramento. A separate report of the recovered gauge was received from the Department of Energy Radiological Assistance Program, Region 7, after they received a report from Sacramento Hazmat of the recovered gauge. CDPH-RHB opened an investigation on March 26, 2021 to determine the gauge owner (Construction Testing Services, Reactor Materials License Number 6431), and the circumstances of how the Troxler gauge (partial serial number 12475) ended up abandoned on the side of Jackson Highway in Sacramento. California Event No: 032621 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.
