| Title | Agreement State Report - Potentially Stolen Moisture Density Gauge |
| Event Description | The following information was obtained from the State of Colorado via email:
On Thursday August 2, at approximately 0840 MDT (Mountain Daylight Time) a portable gauge licensee (AG Wassenaar, Inc. License 212-01 Amendment 21) based in Denver, Colorado notified the Colorado Department of Public Health and Environment (CDPHE) Radioactive Materials Unit on-call duty officer that a gauge was missing and possibly stolen. The gauge had last been seen on Monday July 30 at 4:00 pm at the temporary work site. Upon returning to the office, the gauge user unlocked the box but became distracted and did not check-in the gauge. The gauge user then returned to his residence and parked his truck. The employee did not return to work until the morning of Thursday August 2nd, when he realized that the gauge was not in its case in the truck. The employee believes it may have been stolen from his residence on Tuesday night, however the licensee's employees are currently searching the residence, surrounding neighborhood, and last job site. The gauge involved was a Troxler model 3430 (gauge serial number 26071), containing 8 mCi of Cs-137 (serial #75-9099) and 40 mCi of Am-241:Be (serial #47-22450). The licensee was instructed to conduct a thorough search for the gauge in all known locations where it could be, and to also notify the local police should it not be found within the hour. Additional information and an incident report from the licensee is pending. 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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf This source is not amongst those sources or devices identified by the IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source |
