OK, i just realized that there is a bit of a problem with a previous thing i thought was missing from the book: The sniffer planes telling us exactly what it was that exploded there. Country of origin and yield.

What is really missing is that this was one of the biggest nuclear reactor accidents the world has seen, too. Two reactors, that had been running for years, and that contained a lot of nasty radioactive fission products, just vaporize, or at leas aerosolized. All that corium that is left in Chernobyl did not travel around the world and poison people elsewhere. Here all the spent fuel is going on a trip. And nobody around the world, not Greenpeace, not everyone, has any concerns about that. Meh.

Oh, the problem: you have different sources of fission products and fissile material. Maybe you can tell them apart? At least it complicates the affair.
