| Event Description | The following information was provided by the licensee via phone and email:
Agilent Technologies manufacturers ECDs [Electron Capture Detectors], containing 15 millicuries each, of Ni-63 for use in Gas Chromatographs (for generation of ionized atmospheres for chemical analysis). We have a number of ECDs in use at our facility as addressed below for customer support and R&D. We are required by our license to perform wipe (swipe) tests every six months. The ECD in question was last wiped in August. We were in the process of performing our most recent wipe test last month (February) when we discovered the ECD and its host GC were no longer in the lab they were being used in. [Source was determined to be missing on February 22, 2022 at 1000 EDT when it could not be found for the scheduled swipe test.] We discovered quickly that the individual chemist with ownership of the ECD retired in November of 2021 [last date the device was accounted for]. Investigations to date have not been successful in recovering the ECD. Information pertinent to the incident to follow. I will also be submitting a letter to the appropriate address in one month if we are still unable to recover the ECD. ECD Serial Number # U25487 Activity: 15 millicurie Ni-63 Facility security: Access to building is limited to those issued electronic badges. Labs are further secured by electronic access only to necessary personnel. [Therefore the source is not suspected to have been stolen.]
The following information was provided by the licensee via phone: The source is still lost. The licensee is submitting a written report to Region 1. Notified R1DO (Dentel), ILTAB, and NMSS Events Notification by email. 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.
