The following information was provided by … The following information was provided by the licensee via phone and email:</br>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.</br>ECD Model # G2397A</br>ECD Serial Number # U25487</br>Activity: 15 millicurie Ni-63</br>Facility security: Access to building is limited to those issued electronic badges.
