| 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) |

| coin-counting | A sliding movement of the tips of the thumb and index finger, occurring in paralysis agitans. (05 Mar 2000) |
| whole-body counting | Measurement of radioactivity in the entire human body. (12 Dec 1998) |
| Zappert counting chamber | A special, standardised glass slide used for counting cells (especially erythrocytes and leukocytes) and other particulate material in a measured volume of fluid; the central portion is precisely ground in such a manner that the uniformly flat surface is exactly 0.1 mm lower than that of two parallel ridges on which a special, uniformly flat coverslip may be placed; accurately etched lines on the flat central portion form the boundaries of groups of squares of known areas, thereby providing the basis for determining the volume of fluid in which the cells are counted. Glass slides of this type are frequently known as haemocytometers. (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 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) |
| airbrasive technique | A method of grinding, cutting tooth structure, or roughening the natural tooth surface or the surface of a restoration, by means of a device utilizing a gas-impelled jet of fine Al203 particles which, after striking the tooth, are removed by an aspirator. See: microetching technique. (05 Mar 2000) |
| air-gap technique | Chest radiography performed using a space between the subject and film instead of a grid to absorb scattered radiation; usually requires a target-film distance of 10 feet. (05 Mar 2000) |
| aseptic technique | <procedure> A method used by microbiologists and clinicians to keep cultures, sterile instruments and media, and people free of microbial contamination. (09 Oct 1997) |
| atrial-well technique | An obsolete semi-closed surgical technique for repairing atrial septal defects and other cardiac abnormalities. (05 Mar 2000) |
| Barcroft-Warburg technique | An apparatus for measuring the oxygen consumption of incubated tissue slices by manometric measurement of changes in gas pressure produced by oxygen absorption in an enclosed flask. Synonym: Barcroft-Warburg apparatus. (05 Mar 2000) |
| Begg light wire differential force technique | An orthodontic appliance utilizing small gauge labial wires with expansion and contraction loops formed into it and attached to bands fitted to individual teeth; sometimes called Begg light wire differential force technique. (05 Mar 2000) |
| Berk Sharp technique | <molecular biology, procedure> A technique of genetic mapping in which mRNA is hybridised with single stranded DNA and the nonhybridised DNA then digested with S1 nuclease, the residual DNA that hybridised with the messenger is then characterised by restriction mapping. (18 Nov 1997) |
| scintillation counting technique |
a method of determining the amount of radioactivity by use of a scintillation counter (qv).
