AbstractAbstract
[en] Radiographic exposure can be determined by either trial exposure, reference to previous data or using exposure chart. Without previous data, exposure chart is the easiest and economic way to achieve correct exposure. It will minimize re-shoot and time. This paper presents the development of gamma exposure chart for Selenium-75 source. Film radiography method has been chosen for this development using steel step wedge blocks. Agfa Structurix D7 films have been used during the exposure and the optical density of the films was measured by using X-Rite densitometer. Method of development of the chart is explained. The chart is tested on pipe and welded plate test sample and the results are discussed. (author)
