Tracking Fukushima Radiation:

Since the Tohoku earthquake and tsunami crippled Japan's Fukushima Daiichi nuclear power plant in 2011, concerns have spread among the public that water with traces of radioactive material might be traveling in a plume across the Pacific Ocean toward the west coast of North America.

Experts say the radiation levels reaching the U.S. coast and Hawaiian Islands will be too low to threaten human health or marine life, but no U.S. government or international agency is actually monitoring radiation in these places.

Now, a scientist at the Woods Hole Oceanographic Institution (WHOI) in Massachusetts is launching a new citizen science project to measure levels of radioactive cesium in water washing up along the West Coast.
