A radiation detector is a device used to measure and identify the presence of ionizing radiation, which can come from sources like radioactive materials or nuclear reactions. These detectors can sense different types of radiation, including alpha particles, beta particles, and gamma rays. They are commonly used in various fields, including nuclear medicine, environmental monitoring, and nuclear power plants, to ensure safety and compliance with regulations. There are several types of radiation detectors, such as 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 popular for their simplicity and effectiveness in detecting low levels of radiation,
