The following information was received from the Commonwealth of
Kentucky via facsimile:
KY RHB [Kentucky Radiation Health Branch] Inspector, Christopher Keffer, was performing a routine health and safety inspection of the licensee when the RSO [Radiation Safety Officer] discovered that a stored device was missing. According to the RSO, the laboratory where the device was stored was cleaned out the week before; it is currently believed that the device has been thrown away and is now in a landfill.
The sealed source identification number is NR-536-D-808-B associated with a Perkins Elmer Clarus Model 500. The source is a Ni-63, 15 microCurie source.
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.
