Аннотация

Problems associated with the radiography of objects made of steel having thickness of 100 mm and more are outlined. The classical method of gathering information provides for mounting semiconductor photo detectors directly on scintillators. As a result, gamma radiation scattered in a scintillator enters photo detector increasing the image noise and providing a negative effect on processing electronics. A method to design a recording system using a wavelength-shifting fiber having no disadvantages of the classical technique is proposed. This method makes it possible to decrease the image noise, to remove electronics from direct effect of gamma radiation and to increase the registration efficiency. Various approaches of implementing the method proposed to detect signals are explored experimentally with selecting the optimal techniques. This research enabled developing a design base to engineer recording element. The results on measuring parameters of the registering element are presented.
