'''Radiation''' is the travel of energetic particles through space. It takes different forms and can be divided into ionizing and non-ionizing radiation.
    
Non-ionizing radiation is emitted from many everyday devices, like [[mobile phone]]s, [[microwave oven]]s, and [[television]] signals.

[[Alpha]], [[beta]] and [[gamma]] ionizing radiation is emitted from various materials used in [[nuclear power]] stations. Radiation is emitted as either [[particle]]s or [[wave]]s. The nuclear discharges from a nuclear power plant are well within all the limits set by the government and by nuclear industry regulators. These are limits that are set to maximize safety for the workforce, the local community and the region. Discharges into the sea and air are constantly measured to ensure that people and the environment are not harmed. The radiation exposure that people receive is monitored to ensure that it meets all the limits set down by the regulators and by internationally accepted practice.

Radiation is also one of the three primary modes of heat transfer. All matter with a temperature above [[absolute zero]] emits thermal radiation.
