Scientists from the Woods Hole Oceanographics Institution have found signs of contamination off the Pacific Northwest Coast.
In a statement released this week, marine radiochemist Ken Buessler says that while the levels remain well below safety limits for human health and marine life, they do need to be closely monitored.
The highest level of the isotope cesium-134, which is the “fingerprint” of Fukushima, was found from a sample collected about 2500 kilometres west of San Francisco. However, those levels still fall well below government safety levels for drinking water, swimming and other recreational activities.
Buesseler’s work did not sample sea life, but Canadian scientists working under InFORM have sampled fish off the coast of B.C. and did not find any Fukushima cesium.
