WebRadiation is the emission (sending out) of energy from any source. X-rays are one example of radiation, but so is the light that comes from the sun and the heat that constantly comes off our bodies. When talking about radiation and cancer, many people think of specific kinds of radiation such as x-rays or the radiation made by nuclear reactors. WebLight is electromagnetic radiation which is visible by the human eye and has a wavelength between 400 and 780 nm. (1 nm = 10-9 m). Visible light constitutes a very small part of the whole electromagnetic spectrum and for instance, ultraviolet radiation covers the range from 100 nm up to 400 nm, and infrared (IR) radiation from 780 nm up to 1 mm.
