AGREEMENT STATE - SOURCE DISPOSAL RECORDS UNAVAILABLE The State provided the following information via email: "On 09 January 2006 Washington Office of Radiation Protection received written notification from Multicare that Multicare could not account for transfer / disposal of 12 (twelve) Gadolinium-153 radioactive sealed sources (260 microcuries, 9.6 Megabecquerels total activity on 09 January 2006). The notification was in response to an Item of Noncompliance issued to Multicare for incomplete transfer / disposal records. The licensee believes that the sources were properly disposed of around December 2003, but incomplete records cannot confirm this. Complete records for similar sources confirm proper disposal of similar sources around similar time frame. [The Washington Office of Radiation Protection] investigation continues." Washington State Report #WA-06-003 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 |
