Chornobyl and independence in 1991, sentence 6

On 26 April 1986 reactor 4 of the Chornobyl nuclear power plant exploded; about 31 people died in the first months, tens of thousands were evacuated for good, and later deaths from radiation (invisible harmful rays) are debated, because cancers can appear years later and also have other causes, with estimates from thousands to tens of thousands.

Who acts: reactor, 31 people, cancers · What happens: explode, die, evacuate, debate, appear, have · To what, where: 26, tens, later deaths, other causes
