Ydinpolttamista
Ydinpolttamista refers to the process of nuclear fission where a fissile atom, typically uranium-235 or plutonium-239, absorbs a neutron and splits into two or more lighter nuclei. This splitting releases a significant amount of energy in the form of heat and gamma radiation, as well as additional neutrons. These newly released neutrons can then go on to induce fission in other fissile atoms, creating a self-sustaining chain reaction.
The concept of nuclear fission was first experimentally demonstrated in 1938 by Otto Hahn and Fritz Strassmann,
Uncontrolled nuclear fission forms the basis of nuclear weapons. In a nuclear explosion, a rapid and exponentially
