Abstract		Imaging Plates (IP) are recently developed sensitive integrating detectors based on the effect of photo-stimulated luminescence (PSL). Verious types of IPs sensitive for X- and gamma rays, electrons and other heavier charged particles as well as for neutrons are commercially available. The imaging system consists of a flexible large area (e.g. 25 cm by 40 cm) IP, laser based scanning image reading unit, image processor and image printer. The imaging characteristics of the IP system are broad linear response and dynamic range, excellent spatial resolution comparable to X-ray films, very high detective quantum efficiency, very small image distortions and the reusability of IP. The first IP detector systems were intended for medical diagnostics and applications in medical autoradiography and in electron and X-ray diffraction studies. However, recently developed IP systems enable excellent applications of IP also in the field of NDT, in particular in neutron radiography and in X- and gamma ray raidography. In the paper the principles and characteristics of the IP systems are summarized. Various application possibilities of IPs in radiography with neutrons, X-rays and electrons are described. Applications of IP in autoradiography, dosimetry and radiological protection are considered.
