The following information was provided by the
Illinois Emergency Management Agency (the Agency) via email:
The Agency was contacted on 3/11/22, by the Radiation Safety Officer for Heuft USA, Inc to advise that a package scheduled to arrive at their Downers Grove, IL facility on or before 3/10/22, had not arrived. This was reported as missing in transit. The 6"x6"x6" excepted package contains approximately 86 mCi of Am-241. The carrier could not immediately locate the package and advised it had not been checked into any of their processing facilities. Last known location was an industrial facility (S.C. Johnson) in Sturtevant, WI on 3/3/22, when it was packaged for transit and picked up by the carrier. The package contained (2) special form model AMC-25 sealed sources containing approximately 43 mCi of Am-241 each. Source serial numbers were 3676CW and 7256LQ. Both sources were contained in the 6"x6"x6" brown cardboard box. As it is an excepted package, it will bear only the terms `UN2910' and `RQ' (reportable quantity), and not radioactive labels. Should the package be opened, there is an aluminum 5"x5" round can filled with foam and two zip lock bags. Each bag contains a shielded source holder with the Am-241 capsules therein. The bags and the can are labeled with a trefoil and the words `Radioactive Material'. Unshielded, the two sources would yield a combined exposure rate of about 15 mR/hour at one foot. This is not an immediate hazard to workers or members of the public that locate the package. There is no indication of intentional theft or diversion.
Item Number: IL220009
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.
