The following information was received via fax:
On Friday evening we received a call from the [after-hour phone] service with instructions to call the SOC concerning a lost nuclear gauge. There were instructions to call [the] RSO for Pre-Test Lab [TXRAML02524] a licensee based in Georgetown, TX with authorization to possess and use a variety of moisture/density (M/D) gauges. The RSO explained that around 1500 hrs on Friday, March 10, 2006, one of his trucks was proceeding to a convenience store in the vicinity of Red Bud and County Road 122 in Round Rock, TX when upon arriving at the store it was noticed that the M/D gauge was missing. He admitted that the tailgate may not have been secured and the shipping container was not chained to the bed of the truck. An extensive search of the area traveled was conducted by Pre-Test as well as Round Rock PD and FD without finding the container. The device is a Troxler Model 3411-B serial number (S/N) 10260 with a 9mCi [milliCurie], Cs-137 source model TEL Dwg. #102112 , S/N 40-7662 and a 44mCi, Am-241source model TEL Dwg. #102451, S/N 46-1663.
Texas Incident No.: I-8312
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.
