The following Radiological protection instruments can be used to detect and measure ionizing radiation: Ionization chambers; Gaseous ionization detectors; Geiger counters; Photodetectors; Scintillation counters; Semiconductor detectors
Summary of particle detector types. Many of the detectors invented and used so far are ionization detectors (of which gaseous ionization detectors and semiconductor detectors are most typical) and scintillation detectors; but other, completely different principles have also been applied, like Čerenkov light and transition radiation.
A Geiger counter (/ ˈ ɡ aɪ ɡ ər /, GY-gər; [1] also known as a Geiger–Müller counter or G-M counter) is an electronic instrument used for detecting and measuring ionizing radiation. It is widely used in applications such as radiation dosimetry, radiological protection, experimental physics and the nuclear industry.
Detectors are designed to have one or two scintillation materials, depending on the application. "Single phosphor" detectors are used for either alpha or beta, and "Dual phosphor" detectors are used to detect both. [8] A scintillator such as zinc sulphide is used for alpha particle detection, whilst plastic scintillators are used for beta ...
The ionization chamber is the simplest type of gaseous ionisation detector, and is widely used for the detection and measurement of many types of ionizing radiation, including X-rays, gamma rays, alpha particles and beta particles.
A semiconductor detector in ionizing radiation detection physics is a device that uses a semiconductor (usually silicon or germanium) to measure the effect of incident charged particles or photons. Semiconductor detectors find broad application for radiation protection, gamma and X-ray spectrometry, and as particle detectors.
The ionizing radiation used in CT scans can lead to radiation-induced cancer. [13] ... It is commonly used in satellite-based particle detectors, offering several ...
This unit is quite sensitive and can be used to measure low levels of gamma radiation and detect beta radiation. In cases of high-radiation fields, the Geiger tube can saturate, causing the meter to read a very low level of radiation (close to 0 R/h) hence the necessity of the companion ion-chamber survey meters.
