AST has a range of alpha and beta particle scintillators for use in hand-held and fixed scanners that are used to detect radiation in the environment, on personnel and on equipment.

Alpha-Rad for Alpha Detection

A zinc sulphide based scintillator is coated directly on to perspex light guides for use in hand-held probes, fixed in personnel or equipment scanners that are sited at points of entry to, or exit from, high risk areas.  A version is also available on thin mylar sheet where intimate contact between the sample and detector is required such as in radio nucleotide studies.

Beta-Rad for Beta Detection

In order to detect the weak beta signals produced by modern drug, protein and metabolic assays, particle size and deposition must be carefully controlled to ensure maximum surface area of scintillator is available to optimise sensitivity.  To this end AST use specially prepared materials, from anthracene - the benchmark material for beta detection - to size selected yttrium silicate and calcium fluoride powders.

Alpha and Beta Detection

Dual Alpha/Beta-Rad provides both alpha and beta particle detection. A high efficiency zinc sulphide based coating is deposited directly on to a plastic scintillator panel. The zinc sulphide detects the alpha particles while the plastic scintillator detects the beta particles, as well as acting as a light guide feeding the photomultiplier tube that is found in both hand-held and fixed detectors.

Applications:

•  Health and Safety at work
•  Environment monitoring
•  Decommissioning

Benefits:

•  Rapid and efficient scintillators with excellent signal-to-noise ratio, which are ideal for high sensitivity, radiation protection applications.
•  A range of different formats are available to provide the optimum solution whatever the situation
