| ENS 46049 | 28 June 2010 12:00:00 | Agreement State | Agreement State - Moisture Density Gauge Stolen from Job Site | The following information was received from the State of South Carolina via fax: The South Carolina Department of Health and Environmental Control (SC DHEC) was notified on Monday, June 28, 2010 at 8:00 a.m. that a Humboldt Model 5001 B, SN 2508, portable moisture density gauge had been stolen from a job site storage unit in North Charleston, SC. The gauge contained 11 milliCuries maximum of Cesium 137 and 44 milliCuries maximum of Americium 241:Be. (An) F&ME employee, notified the SC DHEC that a gauge technician arrived for work Monday morning and discovered that the job site storage trailer had been broken into. (The site RSO) was notified immediately and he in turn called local police and fire department personnel. He also notified SC DHEC of the occurrence. The RSO indicated that the trailer had been secured on Friday evening (June 25) with the gauge locked in its storage container in the locked storage cabinet within the trailer. No work was performed over the weekend. The theft was discovered, as outlined above, early Monday morning. There were a few other items stolen as well - a GPS unit and a computer. An inventory was still underway at the time of this notification. The local police responders were made well aware of what type of gauge this was and were in the process of filling out the police report. The RSO was advised to fax the police report to SC DHEC once he obtained it. 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 45470 | 27 October 2009 18:00:00 | Agreement State | Agreement State - Moisture Density Gauge Damaged at Construction Site | The following was received from the state via fax: The SC (South Carolina) Department of Health and Environmental Control (SCDHEC) was notified Tuesday, October 27, 2009 at 2:10 p.m. that a Humboldt Model 5001 portable moisture density gauge had been damaged on a job site in North Charleston, SC. The gauge contained 11 milliCurie maximum of Cesium 137 and 44 milliCuries maximum of Americium 241/Be. (The) F&ME employee notified the department (SCDHEC) that a gauge technician had been in the process of performing a standardization test with the gauge when it was hit by a motor grader. (The company representative) was present at the job site when the event occurred. (The company representative) informed SCDHEC that the area had been secured with both the gauge and motor grader within the perimeter. (The company representative) was advised to maintain surveillance of the gauge until SCDHEC personnel could respond. Once on site, SCDHEC personnel determined there was no release of radioactive material and that the Cesium 137 source was still in the locked position. The gauge was placed in its storage container and secured. The licensee informed SCDHEC that he would transport the damaged gauge back to the home office in Columbia, SC that same evening and secure it until the manufacturer could be contacted on Wednesday, October 28, 2009. The licensee would then follow the manufacturer's instructions for the disposition of the device. As more information is available, this notice will be updated. The licensee was advised that a written report detailing this event must be submitted to the department (SCDHEC) within 30 days. The event is open and pending further investigation by the licensee and the department (SCDHEC). Updates will be made through the NMED (Nuclear Materials Event Database) system. | ||
