scattered radiation


Also found in: Dictionary, Thesaurus, Legal, Encyclopedia.

scat·tered ra·di·a·tion

secondary radiation emitted from the interaction of x-rays with matter; generally lower in energy, with a directional distribution that depends on the energy of the incident radiation.
Synonym(s): secondary radiation

scattered radiation

[skat′ərd]
Etymology: ME, scateren, to throw away; L, radiare, to emit rays
photons that move in a different direction than the incident photons that produced them, after the interaction of those incident photons. Also called backscatter radiation.

scat·tered ra·di·a·tion

(skat'ĕrd rā'dē-ā'shŭn)
Radiation that has been deflected from its path by impact with matter. This form of secondary radiation is emitted diffusely by the tissues of the patient during exposure to x-radiation.

Medical exposure occurs in one of the following ways: as primary radiation that passes through the patient, as leakage (ie, radiation that escapes from the protective housing of the x-ray tube) or as internal or external scattered radiation (ie, scattered by the patient due to Compton interactions).
