In 1986 Chernobyl contaminated 21 percent of neighbouring Belarus and 1.5 million of its citizens with radiation.
Chernobyl 's plume was 200 times more radioactive than Hiroshima and Nagasaki combined.
All of the surviving 100,000 liquidators are now ill.
Hundreds have died.
1.3 million hectares of Belarus farmland is contaminated.
Half the radiation contaminated Belarus, Ukraine and Russia.
Half spread over the rest of the world but was not officially studied.
A 30 kilometre uninhabitable zone surrounds Chernobyl.
Taunton is 25 kilometres from Hinkley Point.
374 UK farms including 200,000 sheep are restricted.
Could it happen at Hinkley C?
Industry documents reveal modern reactors more dangerous in an accident than the ones they replace
Independent on Sunday, 8 February 2009 (extracts)
New nuclear reactors planned for Britain will produce many times more radiation than previous reactors that could be rapidly released in an accident.
The revelations - based on information buried deep in documents produced by the nuclear industry itself - call into doubt repeated assertions that the new European Pressurised Reactors (EPRs) will be safer than the old atomic power stations they replace.
Instead they suggest that a reactor or nuclear waste accident, although less likely to happen, could have even more devastating consequences in future; one study suggests that nearly twice as many people could die.
Information in the documents shows that they produce very much more of the radioactive isotopes technically known as the "immediate release fraction" of the nuclear waste, because they could get out rapidly after an accident.
