So what happens when you dump radioactive toxic water into the ocean? The fishes become radioactive! And how do you get people to eat radioactive fish? Set a standard that says how much radiation in fish is OK!
Which is what Japan is doing:
Please. No level of radio active material inside the body is safe. The TEPCO folks are saying the radiation in the water will dissipate. What they don’t tell you is that the little radioactive fish you just ate will continue to give off radiation inside your body.
