A Geiger counter is a metal cylinder filled with low-pressure gas sealed in by a plastic or ceramic window at one end. Running down the center of the tube there's a thin metal wire made of tungsten. The wire is connected to a high, positive voltage so there's a strong electric field between it and the outside tube.

A Geiger counter, also known as a Geiger-Muller counter, is used to detect and measure ionizing radiation. It operates based on the ionization effect produced by radiation when it interacts with matter. The core of a Geiger counter is the GM tube, which is filled with an inert gas, often argon or neon. When ionizing radiation, such as alpha ...

The Geiger-2 portable Geiger counter is designed to go into the water and detect radiation in the water source. This is dependent on the levels being high enough to see. That said, if particles are in the water source, they will make their way through the water and into the gas tube, which will give you a reading.

4. TL;DR -- dead time comes from resetting the detector, not doing this will cause a runaway process. As a quick recap of the way a Geiger-Muller counter works: Radiation enters the chamber, which is filled with a neutral gas (usually He, or Ar). The radiation ionizes gas particles, knocking out electrons, which become free.

A Geiger counter is a charged capacitor with the region between the electrodes filled with a gas (Fig. 1). As ionizing radiation pass through this gas, the molecules of the gas are ionized, so that the gas contains free electrons and positive ions. The electric field in the capacitor separates the ions from the free elections and prevents them ...
