Gamma ray detection is the process of identifying and measuring gamma rays, which are high-energy electromagnetic radiation emitted by radioactive materials. This detection is crucial in various fields, including nuclear medicine, astrophysics, and radiation safety. Devices like Geiger-Müller counters and scintillation detectors are commonly used to capture and analyze gamma rays. These detectors work by converting gamma radiation into measurable electrical signals. When gamma rays interact with the detector material, they can produce light or ionize atoms, allowing the device to register the presence and energy of the radiation. This information helps scientists and safety professionals monitor radiation levels and study cosmic phenomena.
