scintillation counter

n.
A device for detecting and counting scintillations produced by ionizing radiation.

scintillation counter

n
(General Physics) an instrument for detecting and measuring the intensity of high-energy radiation. It consists of a phosphor with which particles collide producing flashes of light that are detected by a photomultiplier and converted into pulses of electric current that are counted by electronic equipment

scintilla′tion count`er


n.
a device that measures radioactivity by registering the number of scintillations it produces.
Also called scin•til•lom•e•ter (sin`tl om′i tər).

If the energy resolution is sufficiently high, we can distinguish the radiation species with very close emission energies in practical applications as scintillation counters.
Tenders are invited for Annual Maintenance Contract For Liquid Scintillation Counters
The solid-state thermal neutron detector provides improvements in sensitivity, size, weight, power consumption, operator safety, transportability and cost compared to other available detectors such as gas proportional counters and scintillation counters," McGinnis said.
Among their topics are scintillation counters, sample preparation, statistics of counting, health hazards and protection, and radiochemical separation techniques.
Beckman Coulter (which together with PerkinElmer makes up 80% of the market) and Amersham Biosciences--two instrument heavyweights--have significant resources invested in scintillation counters, and smaller companies like Raytest and Zinsser have offered their own models for decades.
They tried techniques ranging from the relatively low-tech procedure of searching at night with ultraviolet light (which proved useful) and dowsing (done as a lark) to high-tech methods including ground penetrating radar, proton free-precession magnetometry, scintillation counters (to measure radioactivity), and acoustic diffraction (sound waves).
In the past the material of choice for such scintillation counters was sodium iodide.

However, in its conference call, the company said it had lower than expected sales for its liquid scintillation counters.
This is partly because, although it competes in a number of technologies, it is a leading player only in scintillation counters, a relatively small and obscure market.
