Oh, a 63 yo man who won't have any children anymore and will die in roubdabout 20-30 years will eat the fish? Then it's safe, let's feed the radioactive fish to our children then!
Without knowing the numbers, it's impossible for me to make a judgment call on the release, but it's important to remember that literally everything around you is radioactive. Just because the water has measurable amounts of radioactive material in it does not mean it's unsafe. Ocean water is 3 parts per billion uranium, and yet people happily eat ocean fish.
Again, without knowing the numbers I can't say for sure, but depending on what's in the water (and how much there is) it very well could be entirely fine to dump it.
In any case, yeah I totally agree. It's a publicity stunt.
That water is pretty radioactive at about 1500 Becquerel per liter. It will definitely increase the radioactivity of any seafood caught in the area for a long time. How bad it'll be is not really possible to estimate right now so this is yet another gamble with public safety.
To say it's not possible to estimate is untrue. An international agency determined it would be within accepted safe limits. Still, one can never know and less is certainly better when it comes to radiation.
