The Geiger-muller counter was created by the German physicist Geiger to detect radiation. In 1908, he presented the first effective detector of individual alpha particles.
The Geiger counter works by detecting radiation. It has a tube that counts the number of particles and makes a clicking sound when it is conducting electricity or radiation inside the tube.
Hans Geiger studied radiation in a lot different experiments. He used a gadget known as the Geiger-Marsden experiment in one of his well-known tests. Geiger and his colleague Ernest Marsden used a thin gold foil as the target of an alpha particle beam in their experiment. The majority of the alpha particles, they found, were able to pass through the foil, although a little portion were deflected or even rebounded back. The results of this experiment showed an atom's dense, positively charged nucleus exists.
