Abstract
A highly sensitive Geiger-Mueller radiation detector with improved temperature stability and working life uses a cylindrical cathode made from a nickel copper alloy preferably containing predominantly nickel. This alloy is resistant to attack by halogen quench gases used in the tube and provides an excellent surface for the electrodeposition of platinum to provide a low porosity surface.
