Geiger counters are instruments used to detect if objects are giving off nuclear radiation. They do this by measuring the amount of ionizing radiation. Alpha, beta, and gamma are the three types of ionizing nuclear radiation that the Geiger counters can detect. These devices are used primarily in the fields of physics, medicine, industry, and astronomy. They are also used to test the levels of radioactivity near nuclear power plants and can check for radiation in areas where uranium ammunition shells have been used.
Many people wonder in what year was the Geiger counter invented? The Geiger counter was created in 1908 by a man named Hans Geiger. The first device was only able to detect alpha particles and was not able to detect ionizing radiation until 1928. In 1947 a modern version of the Geiger counter was invented by a man named Sidney H. Liebson. These models are the ones that are currently being used today.
