| ENS 47378 | 27 October 2011 15:27:00 | Agreement State | Agreement State Report - Lost Static Eliminator Containing 10 Millicuries Polonium 210 | The state's licensee reported that they lost a NRD Nuclecel Device Model P-2021-8201, serial number A2HH880, which was shipped to the company on 09/01/10. The company noticed the device was missing on October 4th. However, the company also believes it could be installed somewhere in the facility in a location where it cannot be seen. The State's licensee has implemented the following corrective actions: 1) We will assign 1 device to its own machine cell and it will not be moved. 2) We have stopped the use of quick push/pull connections and replaced with threaded connections. 3) All Nuclecel devices are attached with yellow air hose ... and we don't use yellow air hoses on anything else. 4) We have added the devices to our month end inventory count. 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.

| ENS 44734 | 18 December 2008 06:00:00 | Agreement State | Missing Nrd Static Eliminator | The Agency (Iowa Department of Public Health) was notified by the General License Registrant of a missing NRD Static Eliminator, model P-2021-8201, serial number A2FY911. The discovery was made during the annual renewal of the registration. The RSO for the company stated that the device was used to eliminate static on a part they were molding. The operators had the device hanging over a barrel and apparently the device became unscrewed from the gun and was disposed of in the trash. The registrant has developed a sleeve to assist in holding the device on the guns. In addition, the RSO instructed the shift foremen to check the devices to ensure they are properly secured to the guns. The Agency (Iowa Department of Public Health) called NRD. Inc. to verify that the device was not returned to the manufacturer. NRD Inc. stated they did not receive the device. Corrective Action: (1) Sleeve used to help hold the device on the gun, and (2) Additional oversight to ensure devices are properly secured to guns. The Po-210 source activity is 10 milliCuries. The state considers the material to be lost not recoverable, and the event is closed. Iowa Report: IA080003. 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 |
