according to a june 2012 stanford university study by john ten hoeve and mark z. jacobson, based on linear no-threshold (lnt) model, the radioactivity released could cause 130 deaths from cancer (the lower bound for the estimater being 15 and the upper bound 1100) and 180 cancer cases (the lower bound being 24 and the upper bound 1800), mostly in japan. radiation exposure to workers at the plant was projected to result in 2 to 12 deaths. the radioactivity released was an order of magnitude lower than that released from chernobyl, and some 80% of the radioactivity from fukushima was deposited over the pacific ocean; preventive actions taken by the japanese government may have substantially reduced the health impact of the radioactivity release. an additional approximately 600 deaths have been reported due to non-radiological causes such as mandatory evacuations. evacuation procedures after the accident may have potentially reduced deaths from radiation by 3 to 245 cases, the best estimate being 28; even the upper bound projection of the lives saved from the evacuation is lower than the number of deaths already caused by the evacuation itself.
