The crisis at the Fukushima Daiichi nuclear power plant is prompting countries around the world to reassess the safety of their plants and their nuclear aspirations. Science has created a map that provides a snapshot of the number of nuclear reactors in operation and under construction worldwide, locations of power plants in relation to seismic hazard zones, and reactions to events in Japan in some countries. The rest of this special News & Analysis section examines what we have learned about radiation risks from previous exposures (p. 1504), improvements in safety since the boiling water designs at Fukushima (p. 1506), what to do with the wrecked reactors (p. 1507), and damage to research facilities from the earthquake (p. 1509).
