Semiconductor detectors are devices that use semiconductor materials, like silicon or germanium, to detect and measure radiation. They work by converting incoming radiation into electrical signals, which can then be analyzed. These detectors are highly sensitive and can provide precise measurements of various types of radiation, including alpha, beta, and gamma rays. These detectors are widely used in fields such as nuclear physics, medical imaging, and particle physics due to their compact size and efficiency. They are essential for applications like X-ray imaging and radiation monitoring, helping scientists and medical professionals ensure safety and accuracy in their work.
