Device Manufacturer: Agilent Technologies
Model Number: G2397-65506
Serial Number: U20228
Radionuclide: Ni-63
Activity: 15 mCi

"The reporting requirement is within 30 days in accordance with 105 CMR (Code of Massachusetts Regulations) 120.281(A)(2), missing licensed radioactive materials in aggregate quantity equal to or greater than 10 times quantity specified in 105 CMR 120.297, Appendix C. The Agency considers this event to be open."

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.
