The operation of a scintillation counter involves several key components: a scintillator, a photomultiplier tube, and an electronic system. When radioactive particles strike the scintillator, they produce light pulses. These pulses are detected by the photomultiplier tube, which amplifies the light signals and converts them into electrical signals. The electronic system then analyzes these signals to determine the level of radioactivity present in the sample.
