||Effects of the nuclear accident
|1957, Oct 7
||A Fire in the Windscale plutonium production reactor N of Liverpool, England, released
radioactive material; later blamed for 39 cancer deaths.
|1961, Jan 3
||A reactor at a federal instalation near Idaho Falls, Idaho, USA, killed 3 workers. Radiation
|1966, Oct 5
||A sodium cooling system malfunction caused a partial meltdown at the Enrico Fermi demonstration
breeder reactor, near Detroit, Michigan, USA. Radiation was contained.
|1969, Jan 21
||A coolant malfunction from an experimental underground reactor at Lucens Vad, Switzerland,
released a large amount of radiation into a cavern, which was then sealed.
|1975, Mar 22
||Fire at the Brown's Ferry reactor in Decatur, Alabama, USA, caused dangerous lowering of
cooling water levels.
|1979, Mar 28
||The worst commercial nuclear accident in the U.S. occurred as equipment failures and human
mistakes led to a loss of coolant and partial core meltdown at the Three Mile Island reactor
in Middleton, Pennsylvania.
|1981, Feb 11
||Eight workers were contaminated when over 100,000 gallons of radioactive coolant leaked into
the containment building of TVA's Sequoyah 1 plant in Tennessee, USA.
|1981, Apr 25
||Some 100 workers were exposed to radiation during repairs of a nuclear plant at Tsuruga, Japan
|1986, Jan 6
||A cylinder of nuclear material burst after being improperly heated at a Kerr-McGee plant at
Gore, Oklahoma, USA. One worker died, 100 were hospitalized.
|1986, Apr 26
||In the worst accident in the history of nuclear power, fires and explosions resulting from an
unauthorized experiment at the Chernobyl nuclear power plant near Kiev, USSR (now in Ukraine),
left at least 31 dead in the immediate aftermath and spread radioactive material over much of
Europe. An estimated 135,000 people were evacuated from areas around Chernobyl, some of which
were uninhabitable for years.
|1999, Sep 30
||Japan's worst nuclear accident ever occurred at a uranium-reprocessing facility in Tokaimura,
north-east of Tokyo, when workers accidently overloaded a container with uranium, thereby
exposing workers and area residents to extremely high radiation levels.
