Geiger-Müller tubes are electronic components which enable an instrument to count alpha, beta and gamma radiation events. They do this by converting some of the energy of the radiation event into charge and amplifying that charge using gas avalanche mutiplication so that a usefully large pulse is delivered to the measurement circuit for each radiation event detected.
Our four Geiger-Müller tube platforms are each optimised with different sensitivities, entrance windows and sensitive areas for specific purposes. They are often used in combinations in order to equip an instrument with the widest possible sensitivity range and the confidence of fail-safe operation by including a high-dose rate detection capability.
> General Purpose alpha, beta and gamma
• Our baseline gas volume and mixtures
> High dose gamma
• Smaller volume for lower sensitivity to prevent overload in high flux
> Low dose gamma
• Larger volume for higher sensitivity in low radiation environments
> Contamination monitor alpha, beat and gamma
• Large area and thin entrance window for efficient collection of alpha and beta particles
