The Mullard MX123 is a Geiger-Muller tube with a very thin mica window. The main use is for the counting of alpha and beta particles. The inside of the tube is conducting and is the cathode. The anode is a central rod or wire - probably tungsten. The MX123 has a gas filling of neon, argon and halogen.
