radiation Radiation refers to any process in which radiation is emitted as particles or waves (such as heat, light, alpha particles, or beta particles) from one body, travels through a medium, and is absorbed by another body. Heat transfer by infrared rays is also known as radiation or radiative heat transfer. Infrared radiation travels at the speed of light, can travel through a vacuum, gets reflected and refracted, and does not affect the medium that it passes through. Ionizing radiation occurs in processes associated with nuclear weapons and reactors and the decay of radioactive substances, whereas electromagnetic radiation refers to energy transferred through the whole range of wavelengths and frequencies, as described by the electromagnetic spectrum.
