| ENS 50029 | 11 April 2014 06:00:00 | Agreement State | Agreement State Report - Missing/Lost Portable Gauge | The following was received from the State of Colorado via email: The State of Colorado needs to report a missing/lost portable gauge. The licensee is AG Wassenaar, Inc. (Colorado license number CO 212-01). The gauge is a Troxler model 3430, serial number 36856 with 333 MBq (9 mCi) of Cs-137 and 1.63 GBq (44 mCi) Am-241:Be. The technician who was using the gauge was working at one job site and then drove to a 2nd job site. The technician cannot remember if he placed the portable gauge in the transportation box or not, and whether or not the gauge was secured for transport appropriately. When the technician arrived at the 2nd job site at approximately 1430 MDT on 4/11/14, he noticed that the gauge was missing. The technician and radiation safety officer have traveled the area between the two job sites and were not able to locate the missing gauge. The licensee reported the missing gauge at approximately 1750 MDT on 4/11/14. The investigation by the licensee and the Department (State of Colorado) is ongoing. 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.

| ENS 48152 | 2 August 2012 14:40:00 | Agreement State | Agreement State Report - Potentially Stolen Moisture Density Gauge | 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 |
