Shaped like a pancake, the Pancake Geiger-Mueller (GM) tube provides for a larger detection area compared to a regular cylindrical GM tube. In addition to gamma radiation, the large circular mica window allows beta particles and high energy alpha particles, as well as low dose gamma radiation, to enter the detector. Mica window detectors are suitable for monitoring in a wide variety of environments.
