Alternative form of X-radiation

a form of non-ionizing radiation emitted by the sun and other artificial sources

ionizing radiation that is naturally present in the environment.

High-energy radiation that is capable of causing ionization in substances through which it passes; also includes high-energy particles.

Radiation (quantized as photons) consisting of oscillating electric and magnetic fields oriented perpendicularly to each other, moving through space.

Light emitted by the Cerenkov effect

(physics) The electromagnetic radiation emitted by the acceleration of relativistic charged particles in a synchrotron or under natural conditions approximating those of a synchrotron.

(physics) Electromagnetic radiation having a wavelength approximately between 1 micrometre and 1 millimetre; perceived as heat.

(physics) The electromagnetic radiation emitted from a body as a consequence of its temperature; increasing the temperature of the body increases the amount of radiation produced, and shifts it to shorter wavelengths (higher frequencies) in a manner explained only by quantum mechanics.

(medicine, pathology) Any illness produced by ionizing radiation with symptoms ranging from nausea to death.
