		+	: Radiation is the product of any body that changes from a higher energy state to a lower energy state. For example, when you run a current through a piece of metal it causes the electrons to move to a higher energy state. As they return to a lower energy state, they emit a photon. This is radiation and how a light bulb works. Čerenkov radiation is produced when a charged body slows down to the speed of light in a different medium. In the case of Čerenkov radiation, a proton is slowed down to 0.75 C (the speed of light in water) and gives off photons. A slower proton is at a lower energy state than a fast one. This concept of energy state also applies to the nucleus of an atom.

 I dont think it is the release of particles actually. Is it not matter(particles) converted into energy via E=MC2? The radioactive element Radium for example releases small amounts of radiation by releasing the energy contained within its mass.

There is also a small amount of energy released in the form of kinetic energy (heat) that was previously holding the alpha particle in the nucleus causing the atom to move. It is this heat/kinetic energy that is captured in a fission power plant.
