Scintillation in a sentence

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.

These systems were in turn replaced by scintillation systems based on photodiodes instead of photomultipliers and modern scintillation materials (for example rare earth garnet or rare earth oxide ceramics) with more desirable characteristics.

Usually, in order to detect antineutrinos, тАЬliquid scintillatorsтАЭ scientists need to use a method called liquid scintillation.

An example of this is a scintillation detector used for surface contamination monitoring.

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.

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.

If 1% of the benzene in a modern reference sample accidentally evaporates, scintillation counting will give a radiocarbon age that is too young by about 80 years.

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.

Like gas counters, liquid scintillation counters require shielding and anticoincidence counters.

Of these the scintillation and semiconductor type are the most widely employed.

Radiation-based Gauge: Radiation is passed from a source, through the fluid of interest, and into a scintillation detector, or counter.

Scintillation is defined a flash of light produced in a transparent material by the passage of a particle (an electron, an alpha particle, an ion, or a high-energy photon).

Scintillation-type detectors use a radiation-sensitive crystal, most commonly thallium-doped sodium iodide (NaI(Tl)), which emits light when struck by gamma photons.

The most common types of gamma detectors encountered in NAA are the gas ionisation type, scintillation type and the semiconductor type.

These experiments were begun when Rutherford had noticed that, when alpha particles were shot into air (mostly nitrogen), his scintillation detectors showed the signatures of typical hydrogen nuclei as a product.

They claimed a liquid scintillation detector measured neutron levels at 8 standard deviations above the background level, while plastic detectors measured levels at 3.8 standard deviations above the background.
