Background on the LNT (linear no-threshold) radiation model

Because of the importance of the debate that continues to rage over the harmful effects of low-level radioactivity, I am sending out a copy of my recent exchanges on this topic in the context of the Canadian Pugwash Group. As you know, nuclear proponents have been for many years eagerly pushing the idea that there is a safe threshold of exposure and that exposures below this threshold are either completely harmless or actually beneficial. The latter claim is called “hormesis”.
