| Event Description | The following information was received from the State of California via email:
At approximately 1400 hours0.0162 days <br />0.389 hours <br />0.00231 weeks <br />5.327e-4 months <br /> on Friday, June 20th, Adams Steel reported that a truck from Ecology Auto Parts had alarmed their gate radiation monitors. The truck read 2 millirem per hour at 5 feet away, and about 30 microrem per hour at 20 feet away. The South RM ICE office dispatched an inspector to identify the isotope and assist in isolating the source. The inspector identified the isotope as Cs-137 (nominally 8 mCi), in one of the shrink-wrapped pallets of recyclable metals. Upon removing the shrink wrap, the source rod, index rod, and handle of a moisture-density gauge was identified. The inspector placed the source end of the device in a lead pig, secured the pig in another container, and transferred the device to the radiation control program's southern radioactive materials storage area. Wipes of the other materials on the pallet showed no contamination, and a leak test of the source showed no leakage. The device is part of a Troxler 3430 moisture-density gauge. The americium source was not found. The serial number is 20007. The device originally belonged to United Testing and Inspection, who had reported it stolen March 5, 1993. At that time, the licensee offered a reward for the device, filed a police report, investigated the incident, and took corrective actions (review of all security procedures with employees, upgraded locks on storage area, and limited direct access to the storage area)." CA 5010 Number (Date Notified) - 062008. 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. |
