Personally, I would avoid swimming on Fukushimas public beach. That black tie dressed Mr. Halper reminds us that "there is obviously a difference between caution and hysteria", but in his case I would insist that there is only a thin line between naivity and stupidity. Natural radiation and the massive Fukushima fallout are as far apart from each other as is the amount of hydrochlic acid in your stomach from that in the barrels in my backyard!
Don't trust your local authorities either, they are 1. faking radiation levels and 2. admit the facts only later, when denial is no longer possible!
