Because Dugway did not have a functional irradiation facility, Dugway also sent Ames to USAMRIID for irradiation. Once the samples of Ba Ames were received from Dugwa idials had access. at USAMRIID, irradiaté In particular, remembered irradiating milliliter solution of Ba from Dugway. In a September 16, 2003 interview with related that approximately three to four times, Dugway sent Ba spores to USAMRIID for irradiation. Ivins' lab group was "roped" into the process since they were part of the Bacteriology Division and worked with Ba. After the spores had been irradiated, Ivins! lab group would retrieve them from the cold room in the warehouse near the loading dock. To gain access to the warehouse, the indivi j had to go down the hallway near recalled that the spores may have ‘been in centrifuge bottles that were packaged inside shipping containers. Ivins' group would take the spores to Suite B3 and attempt to grow them on plates as a sterility check. advised that would_not have taken the Dugway spores to irradiated, nor would have picked them up for the sterility check after irradiation.
