scintillation counter

scintillation counter
scintillation counter n a device for detecting and registering individual scintillations (as in radioactive emission) called also scintillometer

* * *

a device to measure and record the fluorescent flashes in a scintillator exposed to high-energy radiation.

* * *

an instrument for indicating the emission of ionizing particles, making possible the determination of the concentration of radioactive isotopes in the body or other substance; the radiation is absorbed by a specific type of crystal or liquid that subsequently emits minute flashes of light, which are detected and amplified by a photomultiplier tube and counted if they fall within a preset window of energies characteristic of the radioisotope in question.
