a sensitive radiation-measuring device that uses a specially coated surface called a phospor to detect radiation; ionizing radiation striking this surface produces bright flashes of light (scintillations). (see radiation detector)
an instrument that measures radioactive decay by sensing the flashes of light produced in a substance by the radiation
counter tube in which light flashes when exposed to ionizing radiation
a transducer that changes the kinetic energy of an ionizing particle into a flash of light
An instrument that detects and measures gamma radiation by counting the light flashes (scintillations) induced by the radiation.
A high speed x-ray detector. Incident x-rays produce flashes of light in a scintillator crystal which are detected by a photomultipler and converted to electrical pulses which can be counted.
A radiation detection and measurement instrument in which light flashes produced in a scintillator by ionizing radiation are converted into electrical pulses by a photomultiplier tube.
A laboratory instrument used to measure how much radioactivity is present in a sample.
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.
An instrument used to detect and measure radioactivity by detecting gamma rays; also called a "scintillometer."
an instrument that measures radioactive decay by sensing the flashes of light that the radiation produces in a detector.
A device containing material that emits light flashes when exposed to ionising radiation. The flashes are converted to electric pulses and counted. The number of pulses is related to dose.
A scintillation counter measures ionizing radiation. The sensor, called a scintillator, consists of a transparent crystal, usually phosphor, plastic (usually containing anthracene), or organic liquid (see liquid scintillation counting) that fluoresces when struck by ionizing radiation. A sensitive photomultiplier tube (PMT) measures the light from the crystal.
