A Geiger counter named after Hans Geiger, a German scientist in the early 20th century who worked on radiation detection, is an instrument that can detect radiation. A Geiger counter (also known as a Geiger-Müller counter) is an electronic instrument used to detect and measure ionizing radiation. It is widely used in applications such as radiation dosimetry, radiation protection, experimental physics and the nuclear industry. The Geiger-Mueller counter, commonly called the Geiger counter, is the most commonly used detector.
A central cable between a high-voltage gas-filled tube is used to collect ionization caused by incident radiation. Although it cannot distinguish between them, it can detect alpha, beta and gamma radiation. Personal radiation detectors or PRDs are portable devices used to detect gamma rays or neutron emissions. These types of devices include dosimeters that can be in the form of radiation plates, dosimeter plates, or other forms of electronic dosimeters.
These devices are used by law enforcement personnel or customs inspectors to detect illegal transportation of radioactive materials. Medical personnel, scientific researchers, nuclear power plant personnel, and hazardous materials equipment also use similar devices. Dosimeter types include single-use film badges and direct-read electronic pagers. A subset of PRDs are spectroscopic personal radiation detectors, or SPRDs, and can measure the energy spectrum of emitted radiation to identify its specific radionuclide.

There are three different main types of radiation detectors:. These are gas ionization based detectors, scintillation detectors and semiconductor detectors.
Radiation detection is achieved through the use of a variety of instruments. The most common type of radiation detector is a Geiger-Mueller (GM) tube, also called a Geiger counter. In the first case (gamma ray recording), natural radiation from the rock is used, while in the second case (neutron recording), a neutron source is used to excite the release of radiation from the rock. A second part of this study was conducted at the EPA's National Air and Radiation Environmental Laboratory (NAREL) to determine if a commercially available radiation detector designed for water systems can show a response to radionuclide injections.
Geiger counters are widely used to detect gamma radiation and x-rays, collectively known as photons, using the windowless tube. A gamma-ray radiation source is mounted on one side of the pipe and a radiation detector is mounted on the opposite side. Radiation detectors can be characterized by the type of radiation for which they are designed to detect or by their underlying operating principles. Ultimately, the detector responded to solid sources that were placed next to the detectors, but the radiation dissolved in the water proved difficult to detect.
When talking about radiation detection instruments, there are three types of detectors that are most often used, depending on the specific needs of the device. The article on the Geiger-Müller tube contains a more detailed description of the techniques used to detect photon radiation. Gas-filled radiation detectors work based on the ionization effect that occurs when radiation passes through air or a specific gas. A radiation detector or particle detector is a device that measures this ionization of many types of radiation, such as beta radiation, gamma radiation and alpha radiation with matter.
The radiation detector is an instrument used to detect or identify high-energy particles, such as those produced by nuclear decay, cosmic radiation, or reactions in a particle accelerator. The result of this action is that the photomultiplier tube generates an output pulse that is proportional to the amount of light energy entering the tube, which in turn is directly proportional to the amount of radiation energy that entered the scintillation radiation detector. Experimental results using alpha particle radiation indicate that the soft error is linearly related to the irradiation time, as well as to the intensity of the radiation source. .
