How Do Nuclear Bombs Work? A nuclear bomb first requires many forces to create. There are tow different types of bombs one using nuclear fusion and one using nuclear fission. When working with both fission and fusion when these changes occur the atoms end up giving off a great deal of heat and energy. These bombs require working with radioactive elements. This meaning not only are you putting people at risk by blowing these bombs up but you are putting yourself at risk by working with the amount of radioactivity that is required, for these bombs. The first type of nuclear bomb is a bomb using nuclear fission. A fission bomb primarily uses U- 235 or other isotopes of U. When the nucleus of these atoms are bombarded by a neutron and capture it the nucleus will split into two smaller atoms giving off a certain number of neutrons in the process. The ejection of neutrons will cause a chain reaction to occur causing the energy given off to be higher. The energy given off is in the form of heat and gamma radiation. Before the explosion the fuel must be separated into subcritical masses as to make sure to not have the bomb explode early. In order for it to work when the masses are brought together they must form a supercritical mass. The two methods to bringing these masses together are gun triggered and implosion. The second type of nuclear bomb is a bomb using nuclear fusion. Fusion bombs are often found to be much more efficient than a fission bomb. Inside the nuclear fusion bomb there is a small fission bomb in aluminum casing. There is a tamper holding the lithium deuterate as to not set the bomb off too early. Once the fission bomb goes off this causes a chain reaction within the bomb melting away the tamper and causing an extreme amount of heat and radiation. These reactions all happen in 600 billionth of a second! There are a large number of risks to using either bomb. The two most obvious effects are a heat wave due to the enormous amount of heat energy given off and a shock wave due to the huge amount of pressure a bomb is put under. Since both types of bombs work with radioactive substances you put yourself at a huge risk of too much exposure to radiation. The effects of radiation can lead to diseases such as cancer which is very life threatening. In all nuclear bombs are not easy things to build. They are also not something you want to mess around with. Both fission and fusion bombs expose you to large amounts of radiation therefore putting you at risk for many health defects. These bombs have been used all throughout history and unfortunately will continue to be used.
