ugh there was 10000kgs in fatman aka 100 sticks
The Little Boy bomb had not plutonium.
In the Nagasaki bomb, about 14 pounds. Design criteria on later weapons is classified.
To make a fission atomic bomb you just take either uranium or plutonium, which are fast-fission materials and find a way to smash the soul out of them so they can make neutrons to continue the chain reaction. You either just take some fissionable uranium, make a bullet out of one and a ball of the other, build a cannon-shaped bomb that shoots the bullet of uranium into the ball of uranium at the end of the barrel - and boom. To make the second kind, you need some plutonium. Plutonium is easy to obtain but it is extremely hard to make into a bomb, because if you shoot two masses of plutonium together like the uranium bomb style, they fission so much easier that they start reacting before they touch and blow themselves apart before anything can fission, so you will need to make a ball of plutonium crush in itself using a shock wave made by a explosion. You surround a ball of fissionable plutonium with explosive stuff. When the surrounding explosives goes boom, the shock waves made by the explosives hits the ball. This causes the plutonium to supercompress itself together - and boom.
Pretty much the destruction of everything in a huge radius.
Cca. 50 kg of highly enriched uranium. Now nuclear bombs use plutonium, not uranium.
Nagasaki (Japan) - 9 August 1945 - a bomb containing 6,4 kg of Plutonium 239
Approx. 10 kg of plutonium 239.
The Little Boy bomb had not plutonium.
Nuclear weapons with plutonium don't contain TNT.
In the Nagasaki bomb, about 14 pounds. Design criteria on later weapons is classified.
That depends, an atomic weapon from WWII was armed with plutonium 239, bombs now use a more dangerous Uranium armament. In order to use the bomb, a smaller explosion much trigger a chain reaction explosion in order to create, for lack of better terms, a "big bang".
