12 miles is the minimum distance of evacuation, peope living 12 to 19 miles from reactors have been told to stay indoors.
Evacuate areas close (2 to 3 miles or 3 to 5 km) to the plant in all directions and a section downwind out to 10 miles (i.e., a key hole effect).
There are many ways a nuclear accident may occur, however most nuclear power plant accident occur due to problem in an reactor.
evacuate the area immediately
The Chernobyl Nuclear Power Plant underwent a level 7 event - the worst accident so far. The plant, located in the Soviet Union near Pripyat in Ukraine lost its number four reactor on 26 April 1986. A link to the Wikipedia article on the accident is provided.
No, not according to an Forbes article that states Chernobyl disaster (level 7 on International Nuclear and Radiological Event Scale) was magnitudes worse than the 2011 Fukushima nuclear disaster in Japan, which was a level 4 and likely be upgraded to a level 5.
what event caused many Americans to worry about nuclear power
Depends entirely on the amount of activity released, so there is no single answer that can be quoted.
Tokaimura nuclear accident happened in 1997.
The term "Broken Arrow" is used to indicate a nuclear accident involving a nuclear weapon that does't pose the threat indicated. The term "excursion" (as in nuclear excursion) or "criticality accident" is applied to a nuclear reactor or nuclear material accident, respectively.
The Chernobyl nuclear accident.
There are many ways a nuclear accident may occur, however most nuclear power plant accident occur due to problem in an reactor.
Those most at risk in a nuclear energy accident are the workers at the nuclear facility itself.
evacuate the area immediately
Three major nuclear accidents; namely:Three Miles Islands nuclear accident, USA, March 1979Chernobyl nuclear accident, Ukraine (former Soviet Union), April 1986Fukushima nuclear accident, Japan, March 2011
Nuclear power accidents are a disaster. The 1986 nuclear accident at the Chernobyl Nuclear Power Plant in Ukraine was a catastrophic accident.
no
The tsunami on 11 March 2011 caused damage and ultimately shutdown of three nuclear reactors in the Fukushima Daiichi Nuclear Power Plant complex in Japan. Residents within a 20 km (12 mi) radius of the Fukushima Nuclear Power Plant were requested to evacuate during the accident.
An nuclear bomb is purposefully release to pulse out damage. A nuclear accident, on the other hand, is an accident when a nuclear source (usually referring to a nuclear plant) either blows up or leaks. Although it is normally weaker and less dangerous than a nuclear bomb, a big enough explosion or a serious enough nuclear meltdown can break that limit.
