In the upper right box are a few links to files exported as OSM, KML, GeoRSS, etc. maybe they can be used or converted? If googles own data can be used that would seem to be most ideal. Assuming that Googles data is correct and up to date…

What is harder to find is info about:
– where radioactive waste is being stored.
– where nukes are stored. (do stored nukes actually radiate?) There are a few known missile bunkers. But only very few known storage bunkers. And then there is still the government that denies that there are still nukes being stored in the suspected bunkers.
– routes where radioactive source and waste material is being transported

It’s a big challenge to actually figure out where radiation is coming from. When a powerplant leaks radiation they will always lie and cover up to try and stop panic, avoid claims, etc. And what part is natural radiation. This makes it very hard to sketch a picture of what is actually true.
