Caption

Figure 1 Schematic of Fukushima Daiichi-derived sources of 137Cs. Atmospheric fallout (?) and direct discharge (?) are shown as total petabecquerels (PBq) released in the first month of the accident (median values from Table 1). Groundwater fluxes (?) and river runoff (?) are approximate ranges for the first year in terabecquerels (TBq), a unit 1,000 times smaller than the PBq used for fallout and direct discharge.
