| Title | Lost Static Eliminators |
| Event Description | On 7/27/07 when completing an inventory, Micron Technology, discovered that nine (9) static eliminators were missing. The company did a thorough search of areas in and around where these instruments were expected to be installed and looked in their warehouse where removed equipment is typically taken when removed from use but the eliminators were not found. The company is continuing its search.
All of the eliminators had Po-210 sources with an activity of about 10 millicuries when purchased. One source was purchased in August of 2003. Four sources were purchased in June of 2005 and four sources were purchased in August of 2005. The company plans on implementing a number of measures to ensure that eliminators are not lost in the future: 1. A cradle to grave tracking system will be implemented along with; 2. implementation of additional training and; 3. procedures for a more structured process from start to finish.
4 of the 9 missing static eliminators have been found and they have been confirmed by their serial numbers. The 4 static eliminators were found inside a purge box. They are being shipped back, today 08/31/07, to the license holder, NRD, which is located in Grand Island, New York. Linda Gersey of NRC Region IV asked Micron Technology to update this event with the above information. Micron Technology is still looking for the other 5 missing static eliminators. FSME EO (S. Wastler) and R4DO (R. Nease) notified. E-mailed to ILTAB.
The 5 remaining static eliminators have been found. The 4 static eliminators were found inside a purge box. They are being shipped back to the license holder, NRD, which is located in Grand Island, New York. The fifth static eliminator was shipped back to the manufacturer in 2004. FSME EO(M. Burgess) and R4DO(C. Johnson) notified. E-mailed to ILTAB. 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. |
