  1. YOU SUCK N00BS tritium is non lethal
    yes germans used it to make hydrogen bombs but in quantities 10,000 times larger
    and besides you probably drnk this much in heavy water

  2. Agreed, you guys are n00bs. Read about tritium before you start spouting nonsense. Futhermore, beta particles from tritium can penetrate only about 6.0 mm of air, and they are incapable of passing through the dead outermost layer of human skin. Eat it.
