those who have responded to this paper in the literature have noted a number of errors, among them that this figure was based on an assumption of acute deaths from low radiation doses. there is no known mechanism for this, and "the cities under study with the lowest radiation fallout have the highest increases of death rates in the 14 weeks following fukushima, while the californian cities that would have received larger doses saw a decrease in death rate growth" and concluded that "innumerable factors other than radiation" were likely responsible for the major part of the variation in us mortality around the time of the nuclear disaster.
