Nuclear Weapons Material

Not to mention the fact that without tritium, the "trigger" for nuclear weapons (and extremely expensive and rare at $ 100m a gram) all you have is a radioactive paperweight.

The "trigger" isn't tritium. Tritium (along with lithium 6) is used in fusion bombs. A fission-only device, ala Hiroshima or Nagasaki, doesn't require any. The trigger in the center of the plutonium core is a neutron source, polonium if memory serves correctly. Tritium is a beta emitter. --Paul
