It's an article of faith that there is no safe levels of radiation. Recently I read a paper which suggested otherwise, and pointed out that survivors of Hiroshima and Nagasaki had a greater life expectancy than the Japanese average. But these days, it's not merely with radiation where people feel that there is no safe level. Current opinion holds that there is no safe level of danger, comfort, shame or suffering. In this episode I examine whether that is in fact the case. And provide evidence that it's exactly the opposite that low levels of harm are not only safe, but actually beneficial.
