Nuclear tests determine the effectiveness and explosive capability of nuclear weapons. Most nations that have developed nuclear weapons have tests of them. Nuclear testing has often been used as presentation of scientific and military strength. There are two types of bombs which release energy from the nuclei of atoms. The simplest kind is an atomic bomb. It releases great quantities of energy through a process called nuclear fission. It is a large unstable (radioactive) element like uranium or plutonium. Another type is the hydrogen bomb, or thermonuclear bomb, which releases an even greater quantity of energy through nuclear fusion.
