The State of
Texas reported that a 55 milliCuries
strontium-90 beta applicator, Amersham Model
SIA.20, is currently missing. The device was formally used at a cancer treatment facility in Plano,
Texas, which has since filed for bankruptcy protection. The device was not returned to the authorized user upon sale of the property. The state believes the device is locked and stored in the building and is attempting to gain access through the bankruptcy trustee. The state is investigating and will provide further details at a later date.

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
