This book aims to educate the reader on radiation detectors, from the sensor to read-out electronics to application. Relatively new detector materials, such as CdZTe and Cr compensated GaAs, are introduced, along with emerging applications of radiation detectors. This X-ray technology has practical applications in medical, industrial, and security applications. It identifies materials based on their molecular composition, not densities as the traditional transmission equipment does. With chapters written by an international selection of authors from both academia and industry, the book covers a wide range of topics on radiation detectors, which will satisfy the needs of both beginners and experts in the field. Features Contain detailed discussions on detector physics. Provides the reader with the basic knowledge on how to design analog read-out electronics for radiation detectors. Includes practical applications of radiation detectors in medical, industrial, and security applications.
