Geiger-Müller Tube

Otto Pressler Company, Leipzig, 1938

In 1928, Hans Geiger and Walther Müller invent a detector for radioactive rays. A metal cylinder contains a rarefied noble gas and an electrode at high voltage. Every particle that strikes an atom of the noble gas triggers a momentary surge.
