A nuclear radiation detector is a specialized device designed to detect and measure the presence of ionizing radiation in its surroundings. Ionizing radiation includes alpha particles, beta particles, gamma rays, and X-rays, all of which have enough energy to remove tightly bound electrons from atoms, creating charged particles (ions). These types of radiation can be harmful to living organisms and pose potential health risks, so monitoring and measuring them is essential in various applications, including medicine, industry, research, and nuclear safety. This article explores the diverse applications of nuclear radiation detectors across different sectors.
