| Title | Agreement State Report Involving a Recovered Source |
| Event Description | At 4:30 pm on 9/9/03 the radiation alarm pegged at off scale at the Keller Canyon Land fill from a load of trash from the Contra Costa Transfer Station. The facility's Bicron probe indicated (off scale) on the drivers side of the truck. The passenger side probe was fluctuating above normal but not off scale. [DELETED], the Operations Manager informed RHB Berkeley of the radiation alarms and that Contra County Environmental Health had also been notified. Based upon this conversation it was determined that the truck will be secured in a restricted area and access will be restricted and warning tape and signs will be used. Arrangements were made to visit the facility on 9/10/03 to determine the cause of the radiation alarms.
The facility was visited on 9/10/03 and after surveys it was determined the source of the radiation alarms was cesium 137. The maximum reading on side of the dump truck was 2.5 milliRem/hr and 0.7 mRem at one meter using an Eberline RO 20 Calibrated 4/03. A Bicron Fieldspec was also used and it was determined that radiation was from cesium 137 based upon the 662 kev gamma photon. The truck was moved to an isolated area and the driver using hydraulics pushed the load out as while surveys were conducted to indicate when the source of radiation had left the truck. Based upon the identification of cesium 137 a sealed source was suspected. After the surveys indicated the source of the radiation was on the ground, rakes and wood were used to move the trash to identify the location of the source. Following surveys and raking, a small one inch cylinder or rod was identified as the source of the radiation readings. The source resembled the end of a moisture density gauge source rod. Based upon surveys it was calculated that the source contained about 8-10 milliCuries of cesium 137. Using tools the rod was placed in a lead pig and transported to CPN for further investigation. The investigation will try to determine if the rod was cut or broken off the source rod and if the serial number on the source can be used to locate it's previous owner. Surveys of the load and truck using a Ludlum Survey meter with a pancake G-m model 44-9 probe indicated their was no contamination from the source. CPN will also perform a leak on the source. Troxler and Pacific Nuclear were also contacted to see if there were any unusual requests for a new source rod in the last six months. Both companies indicated they were not aware of any such requests. Further information will be provided following this investigation. The engraved source capsule serial number is CDCW 556, 9290. This information has been reported to Troxler, Rancho Cordova, who will report it to the RSO, Troxler, North Carolina, where source/gauge/customer files are kept. |
