There were a couple of nutbag doctors a while back publishing papers claiming strong links between radiation from Fukushima and increased deaths here in the US. Even from what they put in the paper, their use of statistics was obviously wrong, and obviously deliberately so. I was going to do it right and post a correction on the web, but I discovered that the CDC won’t give their data out to just anyone. You have to jump through all kinds of hoops to prove that you’re a legitimate researcher, which are really difficult if you don’t have an appropriate institutional affiliation or aren’t in the right field. Eventually I gave up.
