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
