Abstract

Imaging plates (IPs) are recently developed sensitive integrating imaging detectors based on the effect of photo-stimulated luminiscence (PSL). Various types of IPs sensitive to X rays and gamma rays, electrons and other heavier charged particles as well as neutrons are commercially available. The first IP detector systems were intended for medical diagnostics and applications in medical autoradiography and electron and X-ray diffraction studies. However, recently developed IP systems offer excellent applications of IPs also in the field of NDT, in particular in industrial X-ray and gamma-ray radiography and neutron radiography. In the paper principles and characteristics of the IP systems are summarized. Results of the first experiments to evaluate the applicability of IPs in the examination of welded joints are presented. The applicability of IPs as a new image recording system in the radiography of welds was tested on steel test pieces with artificial defects as well as on welded joints with typical defects such as pores and non-metallic inclusions. The results are discussed in view of the comparison with conventional film radiography and experience with IPs already gained elsewhere.
Thanks to some of their advantages IPs will be, in future, seriously competing with X-ray films also in the field of industrial radiography.
