“An analysis carried out by Nature and Columbia University, New York, shows that two-thirds of the world’s 211 nuclear power plants have more people living within a 30-kilometre radius than the 172,000 people living within 30 kilometres of the Fukushima Daiichi plant, who have been forced or advised to leave. Some 21 plants have populations larger than 1 million within that radius, and six have populations larger than 3 million.” (nature.com, map requires Google Maps plugin)
