PORTLAND Ore. (Reuters) - A sample of albacore tuna caught off the shores of Oregon and Washington state have small levels of radioactivity from the 2011 Fukushima nuclear disaster in Japan, researchers said on Tuesday.
But authors of the Oregon State University study say the levels are so small you would have to consume more than 700,000 pounds of the fish with the highest radioactive level to match the amount of radiation the average person is annually exposed to in everyday life through cosmic rays, the air, the ground, X-rays and other sources.
