Two Improved Chemical Agent Monitors (
ICAMs) were lost during a shipment from ORNG [Oregon National Guard] to Guam National Guard. Each
ICAM contains a sealed source containing 10 mCi of
Ni-63. (SSDR NR-1129-D-103-S). The
ICAMs were packaged by ORNG personnel in May, 2007. The missing
ICAMs were reported missing to the licensee on 9 Feb 09. In the weeks following the notification, the licensee conducted an investigation to determine if the
ICAMs were actually lost or misplaced within military control. The licensee believes the two
ICAMs were lost during the transport between Andersen AFB and Guam National Guard between 15-17 Aug 2007.
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.
This source is not amongst those sources or devices identified by the
IAEA Code of Conduct for the Safety & Security of Radioactive Sources to be of concern from a radiological standpoint. Therefore is it being categorized as a less than Category 3 source
