| ENS 53614 | 19 September 2018 07:00:00 | Agreement State | Agreement State Report - Damaged Gauge at Construction Site | The following information was received from the State of California via email: On September 19, 2018, the (Radiation Safety Officer) RSO notified the (California Radiological Health Branch) that a CPN soils gauge, model MC-1DR # MD00605736 containing 10 mCi of Cs-137 and 50 mCi of Am-241/Be had been run over by construction equipment at a temporary job site in Camarillo, CA. The gauge operator had placed the gauge near his test area, but was 15 feet away when the accident occurred. After the accident, he immediately stopped all work in the area and cordoned off an area 30 feet around the damaged gauge before calling his RSO. A radiation survey meter was available from a local radiography company who met the RSO and the gauge operator at accident site. The shaft housing the rod above the cesium source was snapped off from the gauge. The source was in the 'safe mode' during the accident and remained in the shielded area of the gauge. The gauge was able to be loaded into the shipping container for return to the permanent storage location. Radiation surveys were performed with a Bicron GM detector and no contamination was found in the area. The root cause is operator error by the gauge operator. The gauge will be disposed thru the manufacturer (CPN). California Report No.: 5010-091918 | ||
| ENS 42645 | 14 June 2006 07:00:00 | Agreement State | California Agreement State Report - Lost and Subsequently Found Nuclear Gauge | The State provided the following information via email: On 6/15/06, the RSO at Earth Systems Pacific contacted the RHB-Richmond office to report a nuclear gauge incident that occurred in the evening of 6/14/06. On 6/14/06 one of their moisture density nuclear gauges (CPN, Model MC1DR, S/N M10906353 containing 10 millicuries of Cs-137 and 50 millicuries of Am-241) fell off from a back of a truck onto the highway during transportation. A member of the public picked up the Type A container (with the gauge inside) and transported it into the jobsite. The jobsite personnel immediately contacted the Fire Department. The gauge was then handed over to the Fire Department. The Fire Department inspected the gauge and contacted the licensee. On the same day, the Alternate RSO picked up the gauge from the Fire Department and brought it back to the licensed facility. According to the RSO, the gauge was inside the Type A container during the whole incident and there was no visible damage to the gauge. They have performed a leak test and sent it for analysis. The RSO is expecting a report from the Fire Department. The RHB South RM office is awaiting additional information on the incident, including additional information concerning the Fire Department involved, and will investigate the reason the gauge was apparently unsecured in the licensee's vehicle.
