Geiger's

Geiger's can refer to several related concepts, most commonly associated with radiation detection.

• Hans Geiger (1882-1945): A German physicist. He is best known as the co-inventor of the Geiger counter (originally called the Geiger-Müller counter) and for the Geiger-Marsden experiment, which led to the discovery of the atomic nucleus.

• Geiger Counter: A type of particle detector that detects ionizing radiation. It consists of a Geiger-Müller tube filled with a gas at low pressure. When ionizing radiation passes through the tube, it creates an ionization cascade, producing an electrical pulse that can be detected and counted. The number of pulses is proportional to the amount of radiation.

• Geiger-Müller Tube: The sensing element within a Geiger counter. It's a gas-filled tube with electrodes that create an electric field. Ionizing radiation entering the tube causes the gas to ionize, leading to a discharge that produces a measurable electrical pulse.

Therefore, the term "Geiger's" most often implies something related to Hans Geiger's work in nuclear physics, especially the instrumentation he developed for detecting radiation. Context is crucial in determining the specific meaning of the term.
