Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.

So Potentially there's quite a bit more than one cubic meter of active corium and spent fuel at Fukushima. There are around 1000 rods at each reactor - either active or in the SF pool - and each rod holds around 200kg of uranium.

So that's around 200 tonnes. Per reactor.

OK, that'd give you 3 microgram per square meter per reactor that goes boom, if spread evenly across the planet. The potassium background would still be a much bigger problem for anybody not immediately downwind of the plume.

For the people who are downwind of the plume... well, that's a different story, and one where I'm not qualified to come up with even ballpark figures.

Though personally I'd be a lot more worried about Japan having to filter its drinking water for radioactive heavy metals essentially forever.
