Comparison to Images from a Computed Radiography System for Non-destructive Testing Using Selenium-75, Iridium-192, and X-rays

Abstract

A computed radiography (CR) system using reusable image plates (IPs) offers a convenient and reliable way to replace a conventional film-screen system for non-destructive testing field. The ability of radiography to detect a defect in welded objects depends on the procedure and embraces several factors such as the measurement conditions, the image plate type/class, the radiation energy, the radiation type, and the source-to-image plate distance. Also, the ability of images to detect a flaw decreases with increasing object thickness. In the study, images of welded objects were acquired with a CR system manufactured by FUJI by using Selenium-75, Iridium-192, and X-ray with and were obtained through MCNP5 simulations under the same conditions as the given experiments conditions.
