Effective monitoring of the state of critical structures requires continuous improvement of the methods of nondestructive testing (NDT). The E.O. Paton Electric Institute of NASU has traditionally been a leader in this field. Over the recent years, the E.O.Paton Institute has actively conducted work in the field of filmless radiography. For filmless radioscopic control of long-term objects a highly sensitive X-Ray TV detector was developed, which uses an inexpensive stomatological mini-sensor S10811-11 (Hamamatsu Photonics, Japan). Such a detector of extended objects should find wide application in wind, and nuclear power, aerospace industry and other branches, where there is a need to detect cracks with up to 20 ~m opening. The recent developments on tangential radiographing of gas distribution and household lines and other work in the field of monitoring hazardous facilities are presented. 11 Ref., 4 Tabl., 16 Fig.
Keywords: filmless radioscopic control, image stitching, portable detector, stomatological sensor, stomatological sensor, tangential radiographing
