What is a scintillator material?

What Are Scintillation Materials? Scintillators are materials that absorb energetic radiation such as gamma rays, X-rays, or neutrons and convert that energy into short bursts of visible photons. These photons are then converted into electrical pulses by photo-detectors.

What is scintillator crystal?

A scintillation crystal absorbs gamma photons by one or more collision processes and converts some of their energy into visible light and ultraviolet (UV) photons.

What is scintillator used for?

Scintillators are materials that are able to convert high energy radiation such as X or gamma-rays to a near visible or visible light. They are widely used as detectors in medical diagnostics, high energy physics and geophysical exploration (ref. Knoll).

How much does a scintillator cost?

The estimated price for extruded scintillator ranges from $ 3.5/kg to $ 7/kg. About 50% of the cost is due to the raw materials and the remaining 50% is due to processing.

What is the scintillation process?

Scintillation is the process in which the energy from a certain radiation interacting with a volume of sensitive material (called a scintillator) is converted into electromagnetic waves. The frequency of the emitted electromagnetic waves is within or near the visible spectrum.

What is a scintillation vial?

Polypropylene scintillation vials are a general purpose vial that can be used for liquid scintillation counting, gamma counting, chromatography, sample storage and culturing. They provide a high degree of resistance to organic solvents.

How does a scintillator counter work?

Scintillation Counter is Used to Measure Radioactivity Radioactive DNA is mixed with a liquid scintillant. The scintillant molecules absorb the β-particles emitted by the 32P in the DNA, and in turn emit a flash of light. The photocell counts the number of light pulses in a specific time period.

Are scintillation vials glass?

Wheaton™ Liquid Scintillation Glass Vials are manufactured from borosilicate glass. Provides the clarity of glass with the safety of plastic.

How does a liquid scintillation counter work?

The scintillation counter classifies each pulse of photons according to the number of photons in the pulse, which corresponds to the energy of the individual β emission event. Pulses are collated into channels, and the counts per minute (CPM) in each channel is recorded.

What are glass scintillation vials used for?

Scintillation vials are used for assays that use reagents that emit low-energy radiation.

What is meant by liquid scintillation?

Liquid scintillation counting is the measurement of radioactive activity of a sample material which uses the technique of mixing the active material with a liquid scintillator (e.g. zinc sulfide), and counting the resultant photon emissions.
