Chernobyl is as close as it can get to the worst case. The estimation of amount of victims depends on who you ask. There's no dispute about ~30 people who died of radiation. There is a huge dispute about others, with figures going all the way between tens of thousands and about a million. In Fukushima's case, it's also argued that more people died as a result of evacuation than would have died of radiation (if no evacuation would have been ordered). Pro-nuclear groups pull their estimates to one side, anti-nuclear to the opposite side.
