A review of the present status of liquid scintillators is given. The theory explaining the properties of the counters is discussed. Preparation of counters is described and counter characteristics such as emission spectra, response to various nuclear radiations, counting efficiencies, and emission intensities from various scintillating solutions are ...

Proceedings of the IRE, 1949
The scintination counter is a relatively new instrument for the detection and measurement of nuclear and atomic radiations. Light produced in a fluorescent material by the incident particle or quantum Is picked up by a photomultiplier tube. The resultant photoelectric emission is amplified in the photomultiplier by a series of secondary-emission stages.

The scintillation counter as an instrument for in vivo determination of thyroid weight.
Radiology, 1952The scintillation counter—a new name in the rapidly expanding nomenclature of medical science—has been used by other branches of science for only a short time, although the principle was employed by Rutherford and his coworkers at an early stage of their

A high-contrast photographic recorder for scintillation counter scanning.
Radiology, 1956During the past four years, in the Hospital of the University of Pennsylvania, external scintillation counter scanning has been used to provide information relative to the distribution of radioactive isotopes in patients.

A simple, inexpensive gas proportional scintillation counter for X-ray fluorescence analysis
, 1993A simple, inexpensive, high-performance gas proportional scintillation counter for x-ray spectrometry is described. Energy resolutions below 9% are obtained with detector window diameters of less than 22 mm, for 5.9 keV Mn fluorescent x-rays, even for a ...

Nuclear scintillation counters
Journal of the British Institution of Radio Engineers, 1951Nuclear radiations impinging on a phosphor produce short flashes of fluorescence, or scintillations, which may be used to detect and measure the radiations. Major advances have recently been made in this technique, through the introduction of high-gain photo-multipliers to detect the scintillations.

A microstrip gas chamber as a VUV photosensor for a xenon gas proportional scintillation counter
, 1996The characteristics of a one-atmosphere xenon gas proportional scintillation counter (GPSC) instrumented with a novel photosensor are reported. A microstrip gas chamber (MSGC) with a CsI photocathode deposited directly onto its electrode surface is used ...

Neutron Scintillation Counters
IRE Transactions on Nuclear Science, 1956The various types of neutron scintillation detectors are examined with respect to efficiency, background sensitivity, pulse height and time response. Actual performance of certain counters under different source conditions are considered. These are given in Fig. 1, and include a few imaginary (3) cases.
