The licensee's
RSO notified Department of Radiological Health (DRH) about their missing Varian electron capture detectors on 10/15/10, while conducting their six (6) month sealed source inventory and leak tests. The licensee's Receiving and Property Control Office picked the Varian gas chromatograph, Serial No. 10734, up for disposal from one of the licensee's labs and boxed it for shipment to Creative Recycling Systems, Inc., in Palmetto,
Georgia. Creative Recycling Systems received the licensee's recycle trailer on 10/12/10. On 10/15/10, the licensee's property control office contacted Creative Recycling Systems, Inc., and requested notification if the detectors were ever found.
Creative Recycling Systems did not find the Varian electron capture detector containing two Ni-63 sources, serial numbers A2115 and T585, and it is assumed that it has been lost at the recycle facility. The licensee did survey a similar Varian device and found that survey readings were very close to background.
MS Incident #: MS-10006.
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.
