Advances of Radiation Detector Systems in Nuclear Medicine

Abstract

Radiation detector systems are instruments that can identify the presence of radiation in the environment, on the surface and within people. Arguably, no single device can detect all kinds of radiation and no one device is useful in all situations. Understanding of the principles of radiation detection and the characteristics of the commonly encountered detection devices is essential in nuclear medicine imaging. All radiation detector systems share the characteristic that the radiation incident on the transducer produces ionization effects that are not directly observable.
