The Attained Level and Ability of Scientific and Technological Development of Gamma-Radiography

N. R. Kuzelеv, A. S. Sahanov, I. A. Сhepaikin

In gamma-radiography-one of the methods of non-destructive testing, today there is a situation when enterprises use domestic gamma - flaw detectors, developed in the days of the USSR and removed from production more than 25 years ago.
However, gamma radiography is evolving and improving. During this time, new sources of ionizing radiation have appeared, a number of improvements have been made to the design of gamma flaw detectors to improve safety and increase service life, new ways of recording and storing the images obtained, a line of products for gamma radiography for various industries has been formed.
Today we need to pay attention to the automation of the process of radiography, to improve the information content of the control, obtaining quantitative and qualitative characteristics about the object of control.
The issue of improving the protective properties of materials of flaw detectors, for example, by the introduction of nano-additives. This process is at the stage of understanding and requires new solutions.
 
Keywords: gamma radiography, digital radiography, radiometry, computed tomography, welded joints, quantitative characteristics, qualitative characteristics, gamma flaw detectors.
