Dose accumulated during the January (a), March (b), and May (c) 2012 solar events. The beginning and ending times are arbitarily taken to encompass the events. The dotted and dashed lines represent the 30-day limit for lens (100 cGy-eq) and skin (150 cGy-eq), respectively. The GCR background dose rate measured by CRaTER D1-D2, microdosimeter, and RAD has been subtracted out. The small increase in DOY 65 seen by CRaTER D1-D2 and PREDICCS (under 1.0 g cm⁻²) is from the flare that occurred prior to the March 7 event.
