STATUS: closed Licensee: Mikron Industries City and State: Kent, Washington License Number: WN-R0483 Type of License: General License Registration Date and time of Event: 29 June 2005, 10:10 a.m. Location of Event: Kent, Washington ABSTRACT: (where, when, how, why; cause, contributing factors, corrective actions, consequences, Dept. of Health, office of Radiation Protection (ORP) on-site investigation; media attention): ORP was notified, by telephone on 29 June 2005 by a Mikron Industries representative, the company was unable to locate 34 generally licensed Po-210 static eliminators. The devices were received between 15 May 2003 until 21 October 2004. Of the 34 devices, two are NRD Model P-2021 8101 (each originally containing 370 MBq [10 millicuries] Po-210); the remaining thirty-two are NRD Model P-2035 (each originally containing 1480 MBq [40 millicuries] of Po-210). The company seems not to know any more then that the devices are missing. ORP staff will make a site visit 30 June 2005 to help the company with their investigation. ORP staff performed site visits on 30 June and 8 July, 2005. Staff determined from November 2003 until about March 2005 the facility had not properly controlled the licensed material. The facility had not satisfactorily tracked receipt and disposal of the devices. During the visits, staff were able to locate 28 of the 34 missing devices. They had been set aside in work and storage areas. Recovered devices will remain secured on-site until analysis of leak tests will allow for return to the device manufacturer. ORP will follow up with Mikron to ensure proper disposition of the recovered devices. Mikron has instituted management control to ensure proper disposition of devices from now on.

Unknown Activity and pharmaceutical compound intended: N/A Misadministered activity and/or compound received: N/A Device (HDR, etc.) Mfg., Model; computer program: see above Exposure (intended/actual); consequences: unknown Was patient or responsible relative notified? N/A Was written report provided to patient? N/A Was referring physician notified? N/A Consultant used? No Less than the quantity of an IAEA Category 3 source. 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. For some of these sources, such as moisture density gauges or thickness gauges that are IAEA 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. |
