Geiger-Mueller Detector with Tungsten Alloy

Geiger-Mueller detector is a radiation detection and measuring instrument. It consists of a gas-filled tube containing electrodes, between which there is an electrical voltage, but no current flowing. When ionizing radiation passes through and ionizes the gas within the tungsten alloy tube a short, intense pulse of current passes from the negative electrode to the positive electrode and is measured or counted.

A highly sensitive Geiger-Mueller radiation detector with improved temperature stability and working life uses a cathode liner made of tungsten alloy. The tungsten alloy liner is resistant to attack by the halogen quench gases which are used in the detector. The method of conditioning the tungsten alloy tube for use is much simpler and less expensive than it is for existing tubes.

Due to its high density and atomic mass, tungsten heavy alloy exhibits excellent absorption behaviour against electromagnetic radiation such as X-rays and gamma-radiation.A thin layer of tungsten alloy can be used on the inside surface of a cylindrical cathode to give a Geiger-Mueller detector having high sensitivity and outstanding resistance to the halogen gas. Furthermore, it is surprising and unexpected that the tungsten alloy layer can be applied to the interior of a cylindrical cathode as a thin tungsten alloy foil thus omitting the necessity of electrodepositing the layer on the interior surface.
