There is nothing like some Saturday morning hand-wringing left wing tin-foil propaganda to start the day off with. ;)
spike you can blindly believe what antis say or you can read scientific papers, as I have had to for my schooling and work. Again the regulations were developed on the most conservative premise, the linear no threshold theory (LNT)which took the data from the atomic bomb survivors, who receive very high doses of radiation and developed cancers, then they took those points and extrapolated the line to zero. this was done back in the 50's and 50's and this was adopted by regulatory agencies ever since because even if it was wrong, it would not hurt. however, this has cost business and taxpayers billions of dollars over the years. there is actually very good scientific studies that indicate that low doses of radiations actually prevents some cancers, read Andrew Luckey's research on the subject. Here is something more contemporarty you can link to
