Radiation is a form of energy that occurs naturally in the physical world. It is the emission and propagation of energy through space or through matter in the form of particles or waves. There are two types of radiation: ionising and non-ionising. Ionising radiation is capable of breaking up atoms or molecules into pairs of oppositely charged particles or ions; non-ionising radiation does not have this capability.
