Everyone knows about Chernobyl, Three Mile Island and, now, Fukushima. But what about Semipalatinsk, Palomares and Kyshtym? The world is full of nuclear disaster zones -- showing just how dangerous the technology really is.
The Chernobyl disaster still has much to tell us about the long-term risks of low-level radiation exposure. But only if the necessary follow-up studies are supported. (Editorial)
