Plastech contacted the NRC Operations Center to inform us that they performed an inventory on 4/24/07 and identified that an Amstat Industries, Inc.
static eliminator S/N A2DF555, Model - P2021-8101 was missing and presumed lost. The
static eliminator has not been seen since November of 2006. The person providing the report said that the initial activity of the
static eliminator was 10 milli Curies but did not know what isotope was used in the device. Typically Amstat Industries
static eliminators use
Polonium-210. The company recognized the loss during an inventory required to renew their lease.
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.
