0.002 0.001 This is approximately half the dose resulting from atypical routine monthly effluent from Unit 2, due to this release being only trace Cs-137 (the Sr-90 and Ni-63 was completely removed by ion exchange).

There is no dose component from the Kr-85, and H-3 was lower than normal due to no distillate tanks.
