Mixed Waste: RE: P-32 In Region II we use the activities listed in the drinking water limits as a general guidance to clasify something as mixed waste or normal waste. My logic is; if you can drink it from a rad stand point why would it still be waste. Your local state autority or NRC, however, has the final call on the mater.
