I've recently read about these atom bomb tests that frequently occurred semi-near Las Vegas, which people flocked to. Even if they didn't understand the risks at the time, isn't it a serious problem to blast some stretch of land repeatedly with huge explosions?
Didn't they begin the nuclear tests far away from home on some remote islands or something? Why ever bring it "home"? Why not keep making the tests far away? Why take the risk that maybe there is something unforeseen about the a-bombs?
