DETERMINATION OF EXPOSURE CHART FOR FLAW DETECTION IN ALUMINUM MATERIAL USING THE 200EGM RIGAKU X- RAY GENERATOR
Main Article Content
Abstract
This article reports on a research on the construction of a reference exposure chart for aluminum materials with the thicknesses between 10mm and 100mm to determine distance, time exposure. and high voltage using RIGAKU - 200EGM X-ray generator for the purpose of detecting defects and flaws in different components and assembly details. This is not only the important issue in the application of nuclear techniques in industry but also the main method in non-destructive testing in the Training Center, Nuclear Research Institute. The parameters that need to be identified are the distance from the generator tube to the test specimen, exposure time, and voltage. The results obtained are reliable and in line with the standards on industrial radiography. The study contributes to completing exposure charts with high voltages of 180 kV, 190 kV, and 200 kV and effectively exploiting the industrial generator in research and training in the Center.
