The presence of small amounts of radioactive material from the Fukushima Daiichi Nuclear Disaster was detected along the West Coast of Canada across the Pacific Ocean approximately four years after the Fukushima nuclear explosion.
Woods Hole Oceanographic Institution has been collecting data and samples from about 60 different areas; the mainland in America, the west coast of Canada, and the oceans around Hawaii.
The first detected sample of radioactive material was collected, from the Pacific Ocean, about 161km from the northern part of California last November. However, radioactive material had not been detected along the coast of North America.
