| Title | Missing Ni-63 Electron Capture Device |
| Event Description | The Connecticut Department of Public Health Laboratories reported that they were unable to locate a general license Electron Capture Device Ni-63 source. Source serial number is 3359 and was 14.5 mCi in July, 1975.
The last known wipe test of the source was in 2001, conducted when the license was transferred from Thermo-Finnegan to Thermo-Fisher Scientific. The last inventory that positively identified the source was conducted in 2004. Connecticut Department of Public Health possessed the device under general license RC:708101. In May, 2008, the end-user was assembling all known unused sources for proper disposal when they determined that the Ni-63 source was missing. They have performed an extensive search of their facility but have not been able to locate the source. The end-user will be notifying Thermo-Fisher Scientific.
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. |
