      @wellerstein I was just re-reading this and fiddling with nukemap a bit, wondering if you happen to have an idea what the fission fraction actually is on a SLBM MIRV warhead, say the 250kt, or the 800kt Topol?http://blog.nuclearsecrecy.com/2013/08/02/what-the-nukemap-taught-me-about-fallout/ …

      Replying to @Ippus21

      Normal assumption is that 50% is a safe bet but it could easily be a bit higher. Estimate for the W78 (330 kt, 1970s) is 60% fission for example.
