Caesium iodide (CsI), bromide (CsBr) and caesium fluoride (CsF) crystals are employed for scintillators in scintillation counters widely used in mineral exploration and particle physics research to detect gamma and X-ray radiation.
As with most other liquefied noble gases, argon has a high scintillation light yield (c. 51 photons/keV citation ), is transparent to its own scintillation light, and is relatively easy to purify.
In these, the sodium iodide crystals are doped with a small amount of thallium to improve their efficiency as scintillation generators. citation Some of the electrodes in dissolved oxygen analyzers contain thallium.
An example of this is a scintillation detector used for surface contamination monitoring.
Charge and/or scintillation light produced in this way can be collected to produce a detected signal.
However for discrimination between alpha and beta particles or provision of particle energy information, scintillation counters or proportional counters should be used.
