(STATESMANJOURNAL) — Seaborne radiation from Japan's Fukushima nuclear disaster has reached North America.
Scientists at the Woods Hole Oceanographic Institution detected small amounts of cesium-134 and cesium-137 in a sample of seawater taken in February from a dock on Vancouver Island, British Columbia.
It's the first time radioactivity from the March 2011 triple meltdown has been identified on West Coast shores.
