GM Tubes
The correct Geiger-Mueller / Gass Filled tube will provide an easily-used and accurate means of both detecting and measuring most types of radiation. Gas-filled detectors are relatively rugged, low in cost and continue to be one of the most popular radiation detectors. Geiger-Mueller tubes and Helium-3 tubes can be ruggedized to operate in high vibration and high-temperature environments. Furthermore, GM Detectors have an advantage of exhibiting a high degree of immunity when operating in a high Neutron Flux.
John Caunt Scientific is in a unique position in the marketplace where, over the last 40 years, we have been able to build up close relationships with all the major suppliers of Geiger-Mueller and Gas tubes accessible to the UK market. This position gives us an unrivalled portfolio of Gas-Filled detectors to choose from in order to satisfy the needs of all of our customers individually.
GM tubes can be optimized for a specific radiation sensitivity by design modifications in shape, size, and gas formulations.
Due to the popularity of He-3 detectors in oil well logging applications, the detectors are designed to withstand high vibration and high-temperature environments.
