A scintillation detector is a device used to measure ionizing radiation. It works by using a special material, called a scintillator, that emits flashes of light when it interacts with radiation. These light flashes are then detected and converted into electrical signals, allowing scientists to quantify the amount of radiation present. Scintillation detectors are commonly used in various fields, including nuclear medicine, radiation safety, and environmental monitoring. They are valued for their sensitivity and ability to detect different types of radiation, such as alpha, beta, and gamma rays, making them essential tools in radiation detection and measurement.
