Happy 20th Chernobyl
It was only two weeks after the explosion, when radiation releases had tailed off, that the first Soviet official gave a frank account, speaking of the "possibility of a catastrophe".
Official UN figures predicted up to 9,000 Chernobyl-related cancer deaths. But a Greenpeace report released last week estimated a figure of 93,000. Greenpeace said other illnesses could bring the toll up to 200,000.
