The following information was provided by the State via e-mail:
On July 23, 2008, at approximately 10:35 a.m., [the] RSO for Harrington Geotechnical Engineering, Inc., notified RHB about a nuclear gauge (CPN model MC-3 S/N M35116478, 10 mCi Cs-137, 50 mCi Am:Be-241) that had been stolen at a residence (in Westminster, CA 92683, located near the intersection of Magnolia St. and McFadden Ave.) sometime between 8:00 a.m. and 8:30 a.m. Due to an urgent personal need, the operator left the truck outside the residence, with the gauge locked to the bed of the truck by a cable. The cable was cut by the perpetrator to remove the transport case containing the gauge. The Westminster Police Department was notified and a police report was generated (report number 08-06699). The RSO stated that the residence of the operator was in an area that had some gang activity. The RSO was informed of the requirement for a written report within 30-days. The RSO stated that he would place an ad in the newspaper and to offer a reward for the gauge. RHB will investigate this incident.
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.
