Because of the amount of radiation released, Fukushima has been upgraded:
For decades, Chernobyl has reined as the worst civilian nuclear accident in history. But on Tuesday, it got company. Japanese officials raised the level of severity of the ongoing Fukushima nuclear plant disaster to 7, the highest on the International Atomic Energy Agency scale — putting it on par with the April 26 reactor explosion in present-day Ukraine.
“The radiation leak has not stopped completely and our concern is that it could eventually exceed Chernobyl,” an official from TEPCO, the power company which operates the reactors at the Fukushima site, told reporters on Tuesday.
Other estimates I’ve seen say the amount of radiation released from Fukushima is only 1/10 of what was released by Chernobyl. Chernobyl had no concrete containment bunker, so radiation from the meltdown was quickly spread by winds. That’s not the case at Fukushima.
