Gammadetekteerimise, also known as gamma-ray detection, is a scientific technique used to detect and measure gamma rays, which are a form of electromagnetic radiation with high energy. Gamma rays are produced by radioactive decay, nuclear reactions, and other high-energy processes. The detection of gamma rays is crucial in various fields, including astrophysics, nuclear medicine, and security.

Gamma-ray detectors are designed to identify and measure the energy and intensity of gamma rays. Common types of gamma-ray detectors include scintillation detectors, semiconductor detectors, and Compton cameras. Scintillation detectors use a scintillator material that emits light when struck by a gamma ray, which is then converted into an electrical signal. Semiconductor detectors, such as germanium detectors, directly convert the energy of the gamma ray into an electrical signal. Compton cameras use the Compton scattering effect to determine the direction and energy of the gamma ray.

Gamma-ray detection is used in astrophysics to study celestial objects such as black holes, neutron stars, and supernovae. In nuclear medicine, gamma-ray detectors are used for imaging and diagnostic purposes, such as in positron emission tomography (PET) scans. In security, gamma-ray detectors are used to detect illicit nuclear materials and ensure the safety of nuclear facilities.

The development of gamma-ray detection technology has significantly advanced our understanding of the universe and improved medical diagnostics and security measures. Ongoing research aims to enhance the sensitivity, resolution, and efficiency of gamma-ray detectors to further expand their applications.
