CBRN event in Montana, Bozeman area, United States of America on Thu 3rd July 2014

On July 3, 2014, the Radiation Safety Officer (RSO) at Montana State University discovered that a Gas Chromatograph/Electron Capture Detector (GC/ECD) containing a NI63 sealed source was missing from its designated storage location. The RSO had been “the process of disposing of all unwanted/unused sources” when he discovered that the GC/ECD was missing. The GC/ECD was last seen in its designated location three months earlier during a “semi-annual sealed source leak test inspection.” Even following multiple searches by the RSO, the GC/ECD and its NI63 source remain missing and no explanation over its whereabouts has been reached. More comprehensive searches throughout the campus are being pursued.
