The Three Mile Island Unit 2 reactor, near Middletown, Pa., partially melted down on March 28, 1979. This was the most serious accident in U.S. commercial nuclear power plant operating history, although its small radioactive releases had no detectable health effects on plant workers or the public.
What was the worst nuclear accident ever?
Chernobyl Nuclear Disaster

Why was iodine given after Chernobyl?
Chernobyl, the miniseries, insinuates that if people in the areas surrounding the catastrophic explosion had kept a supply of potassium iodide tablets on hand and taken them as soon as the disaster occurred, those tablets would have blocked radioactive iodine from flooding the thyroids of people in proximity to the …

Hiroshima had 46 kg of uranium while Chernobyl had 180 tons of reactor fuel. … While the dose of radiation from the atomic bomb would still give be lethal, all these reasons above combined are why the Chernobyl was much worse in terms of radiation.
What was the most recent nuclear disaster?
The Fukushima Daiichi nuclear disaster was a 2011 nuclear accident at the Fukushima Daiichi Nuclear Power Plant in Ōkuma, Fukushima Prefecture, Japan. The proximate cause of the disaster was the 2011 Tōhoku earthquake and tsunami. It was the most severe nuclear accident since the Chernobyl disaster in 1986.
Is 3 Mile Island abandoned?
Three Mile Island Generating Station Unit 1 (TMI Unit 1) permanently shut down on September 20, 2019, leaving a 45-year legacy of safe, reliable, carbon-free electricity generation and service to the community. It now enters a new era—the safe decommissioning and dismantlement of its components, systems and buildings.
Is 3 Mile Island still radioactive?
The fuel from Unit 2 was removed following its partial meltdown but an unknown level of contamination remains. “No matter how you cut it, Three Mile Island is a radioactive site indefinitely,” said Eric Epstein, an activist who’s followed the site’s legacy for four decades.
