Got a copy of the book. Wish there was a sequel. And yes they changed it from "nuclear war" to a more Weird Science-y explanation... which is unsurprising as science marches on, and the idea of pure radiation, without the intervention and interaction of science stranger than any we know, doing anything but liquefy your DNA has passed out of popular vogue (I blame microwave ovens. Everyone in Western Civilization has seen firsthand what radiation does to organic substances.)
