Scientists have found traces of leaked radiation from Japan’s 2011 Fukushima nuclear accident off the coast of California. Radiation experts, though, say the levels are harmless.
Trace amounts of isotopes linked to Fukushima radiation were detected about 100 miles (160km) west of Eureka, a city in northern California, the Woods Hole Oceanographic Institution (WHOI), a Massachusetts-based research organization, announced Monday in a press release.
Volunteers collected samples found to contain trace amounts of the short-lived isotope cesium-134, considered the ‘fingerprint’ of Fukushima, during a research expedition from Alaska to California. Though cesium-134 is specific to the Fukushima disaster, another form of the isotope, cesium-137, had already been introduced to our oceans during weapons testing in the 1950s and ’60s.
