Radiation detectors are devices used to measure and identify ionizing radiation, which includes particles and electromagnetic waves that can be harmful to living organisms. These detectors can sense different types of radiation, such as alpha particles, beta particles, and gamma rays, and are commonly used in various fields, including nuclear power, medical imaging, and environmental monitoring. There are several types of radiation detectors, including Geiger-Müller counters, scintillation detectors, and semiconductor detectors. Each type operates on different principles and is suited for specific applications. For example, Geiger-Müller counters are often used for personal safety, while scintillation detectors are used in medical applications to detect radiation from radioactive isotopes.
