As it is written on the linked webpage, air pollution kills more than 800,000 people each year. On the other hand, radioactivity arisen from the accident at Fukushima nuclear power plant killed no one.
Despite this fact, anti-nuclear activists say "Even if nuclear power plants are least likely to cause accidents like that, the damage will be extraordinary big once an accident happens. So,all the nuclear power plants should be abandoned immediately."
I wonder how they meausre the size of the damage.
