(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.

Synonym of radiation sickness

(physics) a hypothetical wave, produced by an accelerating mass, that would be propagated at the speed of light

(physics, chemistry) Harmful changes in the properties of materials caused by interactions with ionizing radiation.

(physics, biology) The study of the effect of ionizing and nonionizing radiation on biological systems.

(physics, chemistry) The protection of semiconductor devices from the effects of ionizing radiation.

physical barriers designed to provide protection from the effects of ionizing radiation, including radioactive material / the technology of providing such protection

(physics, chemistry) The study of the chemical changes that result from the absorption of ionizing radiation.

(physics) The pressure exerted by electromagnetic radiation on an object on which it impinges, as a consequence of its momentum.
