For the first time, seaborne radiation from Japan’s Fukushima nuclear disaster has been detected on the West Coast of the United States.
Cesium-134, the so-called fingerprint of Fukushima, was measured in seawater samples taken from Tillamook Bay and Gold Beach in Oregon, according to researchers from the Woods Hole Oceanographic Institution.
Because of its short half-life, cesium-134 can only have come from Fukushima.
