IIX6E02 peaking at several hundred rad/hr, figure 3. NDX7A15 and 8A15 normally see nothing but that's not the case since 0700 this morning, figure 2. IIX8E02 higher than it should be, but tolerable, figure 1. BLA loss signal high even though calibration was done around 1000, bottom panel of figures 1 and 3.
