2500 times the allowable limit off the coast of Japan. They are going to install nets around the area to try to prevent the radioactivity from spreading to othe species and spreading throughout the pacific. Considering this happened years ago isn't building a fence now like closing the barn door after the horse got out 2 days ago? I'm glad I don't like fish, if it spreads to porterhouses I'm screwed.
Given the half life of radiation can be 10,000 years and not yet 2 years since Fukushima a net is not going to cut it, who is going to maintain a net for 10 years let alone 10,000. More than one cow has eaten grass contaminated from the melt down so unless your porterhouse came from south of the equator it most likely did glow in the dark in the last two years.
