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.
