I have no idea what you are talking about. But assuming some mildly contaminated material is indeed used that way - why is that bad? What do you propose instead? Remember - the less contaminated material is, the more there is of it. For example, there will be A LOT (many tons) of ground scraped in various "hot spots" during decontamination, but ground from even the most dirty hot spot is not particularly dangerous. Say, 20000 Bq/kg? As long as no one _eats_ it, it's not a big deal. But where to put all these tons?
Are you done with screaming and ready for adult dialogue?
There is no radioactive flotsam from Japan. If you'd have just a little bit of common sense, you'd know that.
