Also excitations can arise in scintillators ( see scintillation ), whereby light is emitted and then measured by a scintillation counter.

B . Bray, G . A . A simple efficient liquid scintillator for counting aqueous solutions in a liquid scintillation counter.
23.
Subsequent models were the principal instruments used for uranium prospecting for many years, until geiger counters were replaced by scintillation counters.
24.
As the reflectors were manually moved closer and farther away from each other, scintillation counters measured the relative activity from the core.
25.
However, for discrimination between alpha and beta particles or provision of particle energy information, scintillation counters or proportional counters should be used.
26.
High-energy beta emitters, such as phosphorus-32, can also be counted in a scintillation counter without the cocktail, instead using an aqueous solution.
27.
These include scintillation counters designed for freight terminals, border security, ports, weigh bridge applications, scrap metal yards and contamination monitoring of nuclear waste.
28.
Therefore, the radioactive isotope can be present in low concentration and its presence detected by sensitive radiation detectors such as Geiger counters and scintillation counters.
29.
Areas about 12 by 15 feet contain centrifuges, scintillation counters for radioisotopes, refrigerators, and machines to shake microbes either growing in cultures or in storage.
30.
For both the gas proportional counter and liquid scintillation counter, what is measured is the number of beta particles detected in a given time period.
