| scintillascope | <instrument> An obsolete term for scintillation counter. Origin: L. Scintilla, spark, + G. Skopeo, to observe (05 Mar 2000) |

| scintillate | 1. To emit sparks, or fine igneous particles. "As the electrical globe only scintillates when rubbed against its cushion." (Sir W. Scott) 2. To sparkle, as the fixed stars. Origin: L. Scintillare, scintillatum, from scintilla a spark. Cf. Stencil. Source: Websters Dictionary (01 Mar 1998) |
| scintillating scotoma | A localised area of blindness edged by brilliantly coloured shimmering lights (teichopsia); usually a prodromal symptom of migraine. See: fortification spectrum. Synonym: flittering scotoma. (05 Mar 2000) |
| scintillation | 1. Flashing or sparkling; a subjective sensation as of sparks or flashes of light. 2. In radiation measurement, the light produced by an ionizing event in a phosphor, as in a crystal or liquid scintillator. See: scintillation counter. Origin: L. Scintilla, a spark (05 Mar 2000) |
| scintillation camera | Any one of several scintigraphic cameras that records simultaneously counts from the entire operative field of view. Synonym: scintillation camera. (05 Mar 2000) |
| scintillation counter | An instrument used for the detection of radioactivity; the radiation is absorbed by a scintillator (a crystal or a compound, such as POPOP, in solution) which results in minute flashes of light that are detected by a photocathode. The resultant electron emission is amplified by a photomultiplier and an amplifier. Synonym: scintillometer, spinthariscope. (05 Mar 2000) |
| scintillation counting | Technique for measuring quantity of a radioactive isotope present in a sample. In biology, liquid scintillation counting is mainly used for emitters such as (14)C, (35)S and 32)P and particularly for the low energy emission of 3H. Gamma emissions are often measured by counting the scintillations that they cause in a crystal. Autoradiographic images can be enhanced by using a screen of scintillant behind the film. (18 Nov 1997) |
| scintillation proximity assay | Assay system in which antibody or receptor molecule is bound to a bead that will emit light when _ emission from an isotope occurs in close proximity, i.e. From a radioactively labelled ligand. Avoids the need for scintillant in order to measure the amount of bound isotope and thus the amount of antigen or ligand present. (18 Nov 1997) |
| scintillator | A substance that emits visible light when hit by a subatomic particle or x-or gamma ray. See: scintillation counter. (05 Mar 2000) |
| scintillometer | Synonym: scintillation counter. Origin: L. Scintilla, spark, + G. Metron, measure (05 Mar 2000) |
| scintiphotograph | The image obtained by scintiphotography. See: scintiscan. (05 Mar 2000) |
| scintiphotography | The process of obtaining a photographic recording of the distribution of an internally administered radiopharmaceutical with the use of a gamma camera. Synonym: scintography. (05 Mar 2000) |
| scintiscan | The record obtained by scintigraphy. See: scan. Synonym: photoscan, scintigram. (05 Mar 2000) |
| scintiscanner | The apparatus used to make a scintiscan. (05 Mar 2000) |
| scintography | The process of obtaining a photographic recording of the distribution of an internally administered radiopharmaceutical with the use of a gamma camera. Synonym: scintography. (05 Mar 2000) |

| scintillation crystal |
a substance that emits a flash of light (scintillation) when contacted by high-energy particles, such as alpha, beta, or gamma rays, such as a sodium iodide crystal with a trace impurity of thallium used in the Anger camera to detect gamma radiation.
