Radiation and Nuclear

Radiation emergencies can happen because of a terrorist attack or an accident at a nuclear facility.

The worst U.S. nuclear disaster was the Three Mile Island power plant in March 1979. There were no deaths reported, but it took 13 years, at a cost of about $1 billion, to clean up the damage.
