re: Thanks to each of you who has posted to this.
But why go after a bill at all if the leakage was simply below the levels allowed and too low to make any difference?
Sheer politics. A lot of people want the nuclear power industry destroyed, and this kind of thing is a standard technique. It feeds on people who don't have the time or inclination to look more deeply into the facts, and have to rely on newspapers for their information.
We covered a similar issue on this board a while back about a radioactive leak in Japan. The levels were comparable to natural levels in the human body.
