| Title | Agreement State Report Involving an Unaccounted for General License Source |
| Event Description | The following information was received from the State of Mississippi Division of Radiological Health (DRH) via email:
Description of Incident: The licensee contracted with a disposal company to dispose of one (1) Industrial Dynamic Model C1-2C FILTEC source holder, Serial No. 555, source. During the disposal company's visit, it was discovered that the source was not in the source holder and could not be accounted for. The facility has changed ownership in the previous years and the records were not well maintained of receipt/transfer and leak tests. The Industrial Dynamic Model C1-2C FILTEC source holder, contained a 100 millicurie Americium-241 source, Serial No. not known. Isotope(s): Americium-241 Activity: 100 millicuries Date of Incident : unknown Date Reported To DRH: 02-01-10 Mississippi Incident No.: MS-10001
The following information was received from the State of Mississippi Division of Radiological Health (DRH) via email: The licensee performed an investigation into the missing source after receiving a notice of violation issued 03-03-2010. The licensee determined the following from their investigation: (1) Records obtained from Industrial Dynamics, indicated that all sources were removed from the Filtec C1-2C gauges installed at the Vicksburg plant as well as replacement units recently removed. It appears that the source was removed in 1984 from one Filtec C1-2 gauge Ser. No. 00212, and the gauge remained at the plant. The Ser. No. 00212, for the Filtec C1-2C gauge was deciphered only from the inside cover of an instruction manual found at the plant. (2) a sticker, SN:555, was found on or near equipment in storage, but the sticker referenced something manufactured by Nuclear Enterprises Incorporated. The licensee believes the sticker may be referencing a serial number to a machine part and not the source holder in question. This may be where the incorrect reference to a serial number came into question. The licensee believes the former RSO started leak testing the empty Filtec C1-2C gauge Ser. No. 00212, in 2004, and placed a radioactive material label on the empty gauge in 2005, due to the type of equipment it was. (3) The only piece of equipment, a partially dismantled Industrial Dynamics/Filtec C1-2C gauge remaining at the facility may have at one time contained a sealed source. This equipment was inspected by Adco Services , the source holder was found to be empty, and a report issued to DRH on 1-12-2010. (4) The licensee contacted Industrial Dynamics/Filtec and traced the history of source Ser. No. 555. The licensee reported Industrial Dynamics/Filtec claimed the source holder has never been installed in a gauge in Mississippi. The licensee submitted their response and investigative report to DRH on 04-21-2010, and claims it no longer possess any sources of radiation in the state. The violation issued on 03-03-2010 has been rescinded along with termination of GL-154. Notified R4DO (Powers) and FSME (Mauer). 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. For additional information go to http://www-pub.iaea.org/MTCD/publications/PDF/Pub1227_web.pdf 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. |
