scintill-, scintil-, scinti-
(Latin: light, shine, spark, sparkle, twinkle)
2. A tiny flash of light, especially one produced in certain substances (scintillators) when a photon or an ionizing particle deposits energy in the scintillator by ionizing one or more atoms.
Typically there is one scintillation for each ionizing event. The flashes can be counted electronically, and the average count rate then measures the intensity of the incident radiation.3. The action of scintillating; emission of sparks or spark-like flashes of light; a spark.
4. The twinkling or tremulous motion of the light from fixed stars or a rapid twinkling of stars caused by constant small changes in the atmosphere's density.
5. A small flash of visible or ultraviolet light emitted by fluorescence in a phosphor when it is struck by a charged particle or high-energy photon.
6. Figuratively, a flash, a brilliant display (of wit or thought).
2. A phosphor capable of producing scintillations.
2. Sparkling or twinkling.
2. A device containing a scintillator for detecting and measuring low intensities of ionizing radiation.
3. A device for detecting and measuring radioactivity, having a crystal scintillator, a photoelectric cell sensitive to the light from scintillations, and an amplifier.
2. An instrument for measuring gamma rays emitted by a radioactive body.
2. The process of obtaining a photographic recording of the distribution of an internally administered radiopharmaceutical with the use of a gamma camera.
2. The use of scintiphotography to create a map of scintillations produced when a radioactive substance is introduced into the body.
The intensity of the record indicates the differential accumulation of a substance in the various parts of the body.
