There was an interesting opinion piece in New Scientist about radiation safety levels recently (31 July 2010). It looked at health studies from Hiroshima and Nagasaki and studies of chemotherapy patients that suggest that the current recommended radiation limit (1 millisievert per year) is overly cautious. The article went on to suggest that the recommendation be raised to a lifetime total of 5 sieverts at no more than 0.1 sievert per month.

The article is here, unfortunately behind a pay wall: http://www.newscientist.com/article/mg20727715.800-whos-afra...
