Meaning and Definition
A scientific instrument for observing individual scintillations (tiny flashes of light) caused by alpha particles striking a fluorescent screen.
A historical device, invented by Sir William Crookes in 1903, used to visually detect ionizing radiation, particularly alpha particles, through their interaction with a zinc sulfide screen. It is primarily of historical and educational interest in physics.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage. The inventor, Sir William Crookes, was British, giving the term a historical connection to UK science.
Connotations

FAQ
Frequently Asked Questions
No, it is a historical instrument. Modern labs use electronic detectors like photomultiplier tubes or semiconductor detectors for scintillation counting.
It comes from Greek 'spintharis' (spark) and 'skopein' (to look at), so 'spark-viewer'.
Yes, but typically as a educational replica or antique collectible from scientific instrument suppliers, not as a functional research tool.
Early versions often used a small sample of radium or polonium, which emit alpha particles.
