Actually, bgill, Japan has authorized the burning of radioactive sludge and this is contaminating residential areas even more. When very highly radioactive sludge is found, they just mix it with less radioactive sludge to bring the average per kg down and then burn it all anyway - sending into the air to contaminate again.
They have already contaminated the fishing and continue to do so.
In some areas they have the parents and school children scrape up the first few cm of contaminated playground soil but they have no place to put it so they build a mound and put a tarp over it on school grounds. All these alternatives - all they have to do is choose from them for their 3% contamination solution.
Yes, I knew all that. Should have put a /s on my post.
