At 0651 on January 28, 2008, the licensee contacted the State of
California Warning Center /OES to report that a nuclear density
gauge (
CPN, model MC1, serial number MD40807529 - containing [10] milliCuries
Cesium 137 and [50] milliCuries
Americium 241:Beryllium) was
stolen along with the company vehicle that the
gauge was secured within (2005 Toyota Tacoma - Ca license 7W04195). The
gauge was inside the locked transport case. The transportation case was locked and secured to the bed of the vehicle with chains and two independent locks. The
gauge handle was also locked. This was reported to the Palm Desert Police Department (T08028025). The last leak test was performed on December 17, 2007 and was negative for removable contamination.
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.
