The transpacific ocean currents at 2 miles per hour 24 hours a day take about 131 days to reach North America . If it was just a single release it would still be a serious concern . Sadly it is a new plume every minute 1440 times a day . The model below is based on a short release from reactor one . Fukushima has 3 fully melted reactors and fuel pools and is contaminating the pacific ocean at about 50 square miles a day for over 3 1/2 years with no end in site . The homeless who can,t read or write instead of nuclear scientist are doing the most dangerous job on earth bar nothing because nuclear scientist from Yale MIT Stanford Oxford Harvard etc etc are too afraid to go there and that's the sad frighting fact .
