The developed digital radiographic testing technique has brought about change in several industries, including aerospace industry. This paper focuses on the comparisons between conventional and digital radiographic testing for effective aerospace defect characterization in aluminium aerospace component. It presents a detailed methodology and analysis of these two methods. High cost, slow and hazardous productivity are the rigid disadvantages of conventional radiographic testing.

Digital radiography as an alternative technique to conventional radiography stores the image in a radiation sensitive phosphor plate. For the purpose of this paper, the image recorders used are a fine grain film for conventional radiography and a phosphor plate for digital radiography will be used. The results show that digital radiography is an effective radiographic testing technique of inspection on aluminium aerospace components based on the ability for the critical details.
