The State provided the following information via email:
On Tuesday, April 24, 2007, the State of Wisconsin, Department of Health and Family Services, Radiation Protection Section was notified that a CPN Model MCM-2 roofing gauge, containing 50 mCi of Am-241 had been reported stolen near Crete, Illinois. The Department was notified because the gauge is under ownership of a State of Wisconsin company. The gauge appears to have been in the State of Illinois under the control of a company employee that resides in Illinois and is performing work at a client's location in Illinois. The owner did not file for reciprocity with the State of Illinois.
Upon further investigation by the Department, the Department learned that the owner of the gauge does not have a proper Wisconsin Radioactive Material License. The owner received the gauge in a transfer of ownership when the past owner (a Wisconsin Radioactive Material License, #133-1249-01, Roofing Consultants LTD) sold the company to the current owner. The name of the company did not change when the ownership changed occurred, so the company is still operating under the name of Roofing Consultants LTD. The State of Wisconsin is currently investigating this transfer of ownership.
The State of Illinois has been contacted concerning this incident and is in contact with the Will County Sheriff Department. The State of Illinois and the State of Wisconsin will continue to investigate this incident.
Wisconsin Event Number: 07-009
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.
