The following occurred at Joint Base Lewis-McChord which is located in the State of
Washington. At 1330 PDT on 3/20/2015, it was confirmed that items containing general licensed radioactive material had been converted into scrap material and then sent offsite to an as yet undetermined smelter. It is believed that the disposition of this material occurred on 4/30/2014.
The lost general licensed radioactive material was contained in the following equipment with activities as listed:
Smiths Detection, Sabre 4000, Serial #: 43105, 15 mCi Ni-63
Smiths Detection, Sabre 4000, Serial #: 43135, 15 mCi Ni-63
GE, VaporTracer2, Serial #: K190014411, 10 mCi Ni-63
GE, VaporTracer2, Serial #: K190014412, 10 mCi Ni-63
Safran, Itemiser 3, Serial #: 050449010283, 10 mCi Ni-63
The Department of the Army is continuing to try to ascertain where this material ended up. There are no known exposures, injuries or contaminations due to this event.
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.
