According to 'physics for future presidents', the likelyhood of the average person developing cancer is 20%. He says there are 7.2 million people living within 200km of Fukushima. Using the 20% figure that means 1.56 million of these people will develop cancer. So what is this 400,000 number?? That's 1.56 million people of those 7.2 million would have developed cancer even without the Tsunami destroying the nuclear plant.<p>I don't deny that there will be people who will get cancer as a result of this tragedy, but I put very little credibility towards this individual report.
