| Title | Source Holder Malfunction |
| Event Description | On Friday, April 30, 2010, at approximately 1200 EDT, while replacing sources in a Gamma-Metrics Model 2000 Bulk Material Analyzer, it was discovered that the right side source holder had dropped three Cf-252 sources back into the stored and shielded position. Two of the three sources have been recovered, but one remains in the body of the instrument inside the safe and shielded compartment. Exposure rate measurements have been taken and no exposure or safety hazards exist. Efforts to retrieve the remaining source will continue on May 6, 2010.
Each Cf-252 source is 0.8 micrograms, which is approximately 4.3 mCi in activity. 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.
