Says the person who has _never_ drunk "zero" radioactivity water in their entire life. Nothing makes me angrier than flawed reasoning based on linear no-threshold modeling for harms caused by radiation or other contaminants. At some point, you have to consider the realities and practicalities of living in the actual world and recognize that we _must_ accept some reasonable threshold for purity (of anything), because the money it would take to lower it further would be better spent cleaning up some other substance we contact in our daily lives instead.
