Title	Lost and Found Nuclear Density Gauge
Event Description	At approximately 1500 EST, on 11/25/2019, a technician departed a job site when they realized that they left the tailgate opened and the density gauge was no longer in the back of the truck. The technician turned around to look for the gauge, however, the gauge could not be found. The licensee searched for the gauge for approximately 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> and then contacted local law enforcement. The gauge was reported by local law enforcement to have been picked up at approximately 1630 EST. The licensee went to the police department to examine the gauge and it was reported not to be leaking. The gauge information is a Humboldt model 5001C, Serial Number 2301 containing 10 milliCuries of Cs-137 and 40 milliCuries of Am-241. 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.
