I thought the WHO did a study that discovered the effects of mass evacuations were far more damaging than simply staying in the affected areas were - that the stress caused by panic and hysteria over doses of radiation that aren't particularly high is more damaging than the radiation could be. This is the first google result I could find but I'm sure there was a proper report from the WHO.
I also notice that the rhetoric has changed from 'all radiation is deadly evil' to 'ok it's probably not that bad... but you might eat some!!! Horrible death!!!!'. Pro-nuclear types always get moaned at for changing their story, but I notice the anti-nuclear brigade have changed their concerns as well. Is that because of the complete lack of even illness, let alone deaths, due to radiation from Fukushima, including amongst those who are cleaning up the mess? Is it because when people looked at it they realised the linear-no-threshold approach to determining the risk of radiation is pretty weak scientifically (disproven in some studies that found low levels of radiation are beneficial and even necessary)? Is it because a lot of the world is more radioactive anyway and people still live there without coming to a significantly greater level of harm? Is it because although there is a - greater than any nuclear disaster in some cases - risk of floods, volcanoes, hurricanes, typhoons, earthquakes and - not wanting to be insensitive - tsunamis people still seem to live pretty happy lives in those areas?
Perhaps because a couple of years ago the world was ending, Tokyo was going to be evacuated, the US was going to be irradiated as it all drifted across the ocean, dogs and cats would be living together etc. but actually what we have is a lot of water (a lot of which could have just been dispersed in the ocean), a huge decontamination operation (which probably could have been targeted at areas with actual significant radiation rather than just removing inches of topsoil from entire prefectures), no deaths (other than those caused by the evacuation - oh and the 10's of thousands caused by the Tsunami itself). It must be a big disappointment to the serious doomsday-scenario junkies that none of their predictions have come true so far. It is a disaster, but those happen pretty regularly. More people died from car bombs in the middle east last week than due to Fukushima. 300,000 people were evacuated - Syria has over a million registered refugees already and a death toll of 115,000. The Rwandan genocide has a death toll estimated at 500,000-1,000,000. Fukushima was a big accident, will cost a fortune to clean up, but is nowhere near the scale of disaster it's made out to be.
