The following is a synopsis of information received via phone:
On October 3, 2019, at approximately 1900 EDT, a CPN nuclear density gauge containing 10 mCi of Cs-137 and 50 mCi of Am-241 was discovered to be stolen when the person in possession of the gauge found the storage box on his truck open and the gauge not inside. Local law enforcement was notified and subsequently recovered the gauge on October 4, 2019 at 0800 EDT. The gauge did not appear to be damaged and the lock was still intact. The gauge is now in the possession of the licensee.
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.
