VANCOUVER — Ocean-borne radiation from the 2011 Fukushima nuclear-reactor meltdown in Japan has been detected at the British Columbia shoreline, marking the first time Fukushima contamination has made landfall in North America.
The amounts of radiation detected are low and do not pose a health threat to humans, fish or the environment. But the discovery is part of a pattern that is being closely watched by scientists around the world and has mobilized volunteers helping to track the movement of contaminants on ocean currents.
