(The device location is REDACTED). The device is an Ohmart VM00055 that is a part of a mobile vehicle and cargo system made by Science Applications International Corporation (SAIC). The source is a 1.6 Ci, CS-137 source with a source number: 3231CG.
A request made by Headquarters Department of Army Radiation Safety Officer was processed. Notified R1DO (Schmidt), R3DO (Phillips), FSME (Burgess).
The licensee called to clarify that on November 30, 2009, Fort Drum discovered the device was missing and then an investigation ensued. On December 7, 2009, Fort Drum successfully notified the US Army CECOM Life Cycle Management Command that a licensed nuclear scanning device was missing. The device is postulated to be located on a maritime security vessel. Notified R1DO (Schmidt), R3DO (Phillips), FSME (Einberg) 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.
