The genetic effects of nuclear war are of much less concern to me than the immediate (and delayed cancer) somatic ones
Hiroshima/Nagasaki show this all too clearly.
Long discussed UN/AEC studies showed that survivable doses of radiation (say 100-300 rem) barely double the existing genetic
load, and should have an impact on at most 1-3 percent on following generations against a nearly 50 percent lethality on those
Of course, if millions were to be exposed to only sublethal doses, that would loom as a larger catastrophe; but in almost
every imaginable (?) scenario the somatic effects would greatly exceed the genetic ones.
