WebOct 16, 2024 · scintillation counter, radiation detector that is triggered by a flash of light (or scintillation) produced when ionizing radiation traverses certain solid or liquid substances (phosphors), among which are thallium-activated sodium iodide, zinc sulfide, and organic compounds such as anthracene incorporated into solid … WebScintillation detectors work through the connection of a scintillator material with a photomultiplier (PM) tube. The PM tube uses a photocathode material to convert each pulse of light into an electron, and then amplifies that signal significantly in order to generate a voltage pulse that can then be read and interpreted.

WebA unique application of liquid scintillators is in the counting of radioisotopes that emit low-energy beta particles, such as hydrogen-3 ( 3 H) or carbon-14 ( 14 C). As these low-energy beta particles have rather short ranges, they can be easily absorbed before reaching the active volume of a detector.
