Related to scintillation counter: Liquid Scintillation Counter

counter

 [kown´ter]
an instrument or apparatus by which numerical value is computed; in radiology, a device for enumerating ionizing events.
Coulter counter an automated instrument for performing blood counts, based on the principle that cells are poor electrical conductors compared with saline solution.
Geiger counter (Geiger-Müller counter) a radiation counter using a gas-filled tube that indicates the presence of ionizing particles. It is very sensitive to β particles but relatively insensitive to γ and x-rays.
scintillation counter a device for detecting ionization events, permitting determination of the concentration of radioisotopes in the body or other substance.

scin·til·la·tion count·er

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) that results in minute flashes of light that are detected by a photocathode. The resultant electron emission is amplified by a photomultiplier and an amplifier.

scintillation counter

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

scin·til·la·tion count·er

(sin'ti-lā'shŭn kown'tĕr)
An instrument used for the detection and measurement of radioactivity.

Coulter counter
Geiger counter, Geiger-Müller counter
a radiation counter using a gas-filled tube that indicates the presence of ionizing particles.
scintillation counter
a device for detecting beta and gamma rays, permitting determination of the concentration of radioisotopes in the body or other substance. It is more important for gamma rays, which are poorly measured by a Geiger counter.

scintillation

1. the emission of sparks.
2. a particle emitted in disintegration of a radioactive element.

scintillation camera
a stationary device that records a photographic image of the distribution of radioactivity of an organ after the administration of a radionuclide. A sequence of photographs records the uptake and the distribution of the radionuclide.

If the energy resolution is sufficiently high, we can distinguish the radiation species with very close emission energies in practical applications as 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.
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.
