A scintillation counter is an instrument for detecting and measuring ionizing radiation. It consists of a scintillator which generates photons of light in response to incident radiation, a sensitive photomultiplier tube which converts the light to an electrical signal, and the necessary electronics to process the photomultiplier tube output. Scint...

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, spinth...

These devices detect gamma rays and form part of the gamma cameras used in radioactive tracer examinations. Scintillations are flashes of light given out by fluorescent materials (e.g zinc sulphide. When radiation is absorbed by zinc sulphide, it causes the zinc sulphide to produce a small burst of light. These can be electronically counted

A scintillation counter consists of a material that emits light when radiation passes through it. Various liquid, plastic, and crystalline materials have scintillation properties. Scintillation light is measured with photomultiplier tubes. In general the amount of scintillator light detected is proportional to the energy of the radiation.

Instrument for measuring very low levels of radiation. The radiation strikes a scintillator (a device that emits a photon – a single unit of light – when a charged elementary particle collides with it), whose light output is `amplified` by a photomultiplier; the current pulses of its output are in turn counted or added by a ...
