@Picdelamirand-oil it's a technical query. I have seen how people store radio active material safely. A mere 2gm radio active material with 1-1.5 Curie activity is stored in heavy lead container to contain it's activities, the container weigh roughly 15 kg, pretty heavy with respect to the weight of the radio active material. My query is a nuclear bomb contains few kilograms of highly radio active material, then how you are containing it's radio activities safely? Are you using any special material other than lead to contain the radio activities? What is the outer covering of nuclear weapons ?
Why I am asking is I have seen pictures of live US nuclear bomb surrounded by USAF personals , and some of the nuke bombs are so light that it weighs 200-300kg I guess. If a 2gm (cs 137) radioactive material needs 15 kg container,how come a bomb with the few kgs of nuclear material weighs so light?
