Are nuclear accidents dangerous?

Nuclear accidents are extremely dangerous. The accident at Chernobyl, for example, killed a large number of people and caused whole towns to be uninhabitable.

Placing nuclear power in perspective, though, it is overall far safer than coal power. Coal is the largest source of energy worldwide and coal mining, transportation, and pollution from use as a fuel cause a huge number of deaths each year. Mining of coal takes more than 6,000 lives each year in China, for example. Black lung disease causes about 4,000 early deaths each year in the US. Fine particle emissions are believed to cause about 15,000 early deaths in the US each year.
