Japan has now upgraded the accident at Fukushima from level four to level five out of seven on an international scale of nuclear accidents, putting it on a par with the partial meltdown at Three Mile Island in the US in 1979.
They have indeed upgraded the accident to a level 5.
But then the original estimate was that it was a level 5. They then downgraded it to a level 4 …..and have now upgraded it again to a level 5.
We might recall that the TMI incident led directly to a death toll of precisely 0. And that cancer levels were higher from people worrying about it than any radiation received.
There are already (entirely unconfirmed I hasten to add, entirely anecdata) reports of more people suffering from overdoses of potassium iodide than from any effects of radiation.
