Future Hindsight

The Pacific Ocean is Safe After the Fukushima reactor accident, radiation leaked into the Pacific Ocean, sparking global worry. In the months after the accident, levels were high, but not high enough to cause marine life die-off. For the last five years, all fish caught off Japan has been below the radiation thresholds for consumption. Radioactive cesium levels have been low since 2014, and levels of radiation off the California coast are lower today than they were in the 1960s when the US detonated hydrogen bombs in the Marshall Islands. Swimming in the Pacific for eight hours every day is less risky than one dental x-ray. Our Radioactive Ocean A crowdsourced science campaign called Our Radioactive Ocean was created to measure ocean radiation at various points in the Pacific. Interested citizens collected ocean samples and sent them to Woods Hole to be analyzed. The campaign became a hit, and more than 300 data points have been plotted up and down the West Coast. More than 1 million people have visited their
