Thank you, very interesting. Would there be a long half-life from the radiation in the blast? Or would it dissipate rather quickly?
Yes, I was aware of the original yield was supposed to be 100+ Megatons in the Czar Bomba, was the Lead used as a moderator to stop/slow the fission process, and bring down the yield? Certainly Lead is not a supportive material in Fission, unless I'm mistaken? Would Carbon be similarly effective in moderating the yield? I believe Carbon control rods are used in Boiling-Water & Pressurized-Water reactors, correct? |
Fusion creates free neutrons (part of the reason why its effective to use Uranium as the tamper material, since it undergoes fission from these free neutrons) that can possibly ionize other materials, so it depends on what is exposed to the radiation pulse from the blast.
As for Tsar Bomba, lead is actually a good neutron reflector, but it is not reactive like uranium is.
I forgot to mention that the uranium tamper is made of natural uranium, U-238, not the lighter isotope that primary cores are made of, U-235.
