What is the structure of atomic bomb?



Answers:
I guess the better question is, why do you really want to know?
Bomb grade uranium and explosives. The first explosive sets off the uranium in another commpartment and the you get a really big BOOM.
It's available all over the net. Like here for instance.

I wish that it was illegal to put that kind of stuff on the net or even in books.
its big and scary.
it's funny, the president of North Korea asked my that last month, hmmmmmmm? Ask the iraqi's, they have the best in town at the right price.
that should never be revealed to untrained minds. We have enough probklems in ythis world without telling everyone how to construct more chaos!

If you know the answer, please dont write it on the internet!
A big metal thing with fins.
zooooooooooooommmm there goes tony blair, george bush FBI and the bomb squad round to your house.

I agree i dont think things like that should be available to just anyone
same as your head..
A basic fission device (such as exploded by the North Koreans and used at Hiroshima) consists of a sphere of Uranium 235 with a polonium neutron source at the centre. Around the Uranium is a multi-layered high explosive shell.
When the bomb is detonated, the high explosive is detonated from the outside. A shock wave moves in towards the centre and compresses the uranium to a size much smaller than it normally is. This causes it to go super-critical, which means that when neutrons come in to it and split the atoms in the uranium, energy is given off and two neutrons are released. In this supercritical state these two hit more atoms and this becomes 4. And so on - a chain reaction that gets bigger.
This heats the Uranium to around 50 million degrees C, and it goes bang.

If you are thinking of building one, it is quite easy. However to get it to detonate in this nuclear fashion is impossibly difficult because unless you know the correct construction techniques the Uranium will deform into a non spherical shape and the chain reaction will stop. So far only the world's best scientists with billion dollar budgets have done it - nobody else has or could.

Finally if you want a bomb large enough to flatten Birmingham, you need a thermonuclear device. This uses a atomic bomb to heat up a small amount of an isotope of Hydrogen and turn it into Helium - a process called Nuclear Fusion. And this produces very much more energy.
Lisa W while the article is informative and quite fun it does leave a lot to be desired as a guide book. There is no mention of optical cutters or shaping the charge, placement of the detonators, direction of force. I'm almost sure that there are more useful sites that give an in depth view of making an atomic bomb. I to don't think that it's a good idea for this information to be available.
Neils on about a fizzle has the signature of nuclear reaction but not the same damage.
Dude.your not related to Saddam Hussein are you?
I've built one in my shed now, all I need is a large piece of blue touch paper.
