The following report was received via fax:
The licensee submitted a written report June 11, 2008 documenting the loss of 31 mCi of tritium and 0.6 mCi of carbon-14 which had been discovered missing in May 2008.
In September 2004, an incoming scientist brought the materials with him to Wadsworth. Since he was not an authorized. user, the RSO placed the material in a freezer in the chemical storage room. In May 2008 the RSO discovered the materials missing and initiated a thorough investigation. Unfortunately the disposition of the materials remains unknown.
The RSO has implemented corrective actions which include; better inventory practices, increased vigilance over materials in long term storage with an eye towards proper disposal, and no 'general' storage of materials. No reward offered. No press release issued. Incident Closed
New York Event: NY-11-20
New York Incident: 619
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
