   Radiation
   Radiation is a general term for energy which radiates out from a source and which can be particulate or part of the Electromagnetic spectrum . It is more useful to specify the quality of the radiation, for example Ionising Radiation or Non-Ionising Radiation .

    Radiation
    The word 'radiation' can refer to electromagnetic radiation (including gamma radiation) or to alpha and beta particles released from radioactive decay. Radiation can cause ionisation of neutral atoms, by knocking away electrons. This can damage or kill cells. In this way, radiation can cause cancer and be used to treat cancer

    Radiation
    There are two types of radiation - ionising and nonionising. Nonionising radiation from the sun is essential although excess is dangerous. Exposure to all levels of ionising radiation causes complex disturbances in living tissues

15. 
    Radiation
    Radiation simply means the process of emitting energy in the form of waves or particles. For clarity it should be identified by its frequency to be either ionising or non-ionising. A hot water radiator emits electromagnetic radiation in the infrared part of the electromagnetic spectrum and we detect this as heat, sometimes called black heat for i...

    Radiation
    (Radioactivity) Strictly speaking, radiation means giving off any energy particles or waves and includes heat and light. But usually used to mean radioactivity. This means gamma rays, alpha or beta particles from a radioactive source. The radioactivity comes from the breakdown of atoms. The source can be natural or made in a nuclear reactor. Uncont...
