STOLEN PORTABLE DENSITY MOISTURE GAUGE
The licensee left a locked trailer at a job site in Rolla, Missouri Friday evening, 2/28/2020. The trailer contained a locked case, which was chained and locked to the trailer. The case contained a Seaman's portable density moisture gauge, Model Number C300, Serial Number 21274, with a 4.5 mCi Radium-226 source. The trailer, with the gauge inside, was stolen from the job site sometime between Friday evening 2/28/2020 and mid-day Saturday 2/29/2020 when employees of the licensee returned to the job site.

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.
