Waste that needs to be stored for "100,000 to a million years" is not particularly dangerous by definition. Either it's highly radioactive or it has a long half-life. It can't be both. As for the hypothetical "future civilisation" which has somehow lost all our rudimentary knowledge of the physical sciences, but is still somehow capable of deep mining operations is a stupid, absurd canard. Any scenario whereby the knowledge about geiger counters is forgotten is one where that society's problems are going to be far, far more serious than a few deeply buried barrels of lightly irradiated surgical equipment that are statistically impossible to discover by accident. Oh, and you do realise the stuff came out of the ground in the first place? Where's your concern for these future civilisations digging around in natural uranium deposits?
