"medical science tells us there is no safe level..."
Well you're sounding a bit like an evangelist here. Background radiation is here all the time, and X-ray's in moderation are fine (except for developing fetuses). And low levels of radiation are not considered a hazard to medical workers which is why radiology department workers wear devices to monitor cumulative exposure to ensure their safety. The main issues around nuclear power generation center on storage of nuclear waste, hazards from accidents and the potential for proliferation of nuclear weapons. But EDE isn't involved in any of that. It is involved in making better more durable and environmentally friendly concrete and cleaner fuels such as Opitblend and Hythane.
