The State provided the following information via email:
On June 2, 2006, [the] Radiation Safety Officer [for] STATE Testing, LLC, (Radioactive Material License No. IL-1015-01), called to report that a CPN moisture density gauge, Model MC-1, serial no. MD 10900497, was stolen from one of their marked construction vehicles sometime after midnight before six in the morning. The theft occurred while the device was at the operator's home [redacted]. The operator discovered the Ford Ranger truck had been broken into this morning when he was preparing to go to the jobsite. The gauge was reportedly secured in the back of the truck under a locked truck cap by means of a padlock and chain. The operator indicated that the gauge had been further padlocked in the 'off' position. Additional construction equipment that had been locked in the truck was also stolen during the break in. Chicago Police have been contacted and are investigating.
An inspector was sent to the company's 570 Rock Road, East Dundee offices this morning to conduct interviews and gather additional information."
Illinois Report Number IL-060029
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.
