Current topics of industrial radiography and radiation protection

In radiographic testing, radioscopic techniques, the quantitative rating of influence of the film on image quality of X-ray pictures and the ComScan technique, which uses the Compton scattering radiation, are the current topics. In addition, are there important new radiation protection rules available or under preparation which result from amendments of the X-ray Ordinance and the Radiation Protection Ordinance, or from the experience gained during the primary testing of existing, long-in-use gamma equipment. Seminar contributions also consider the effects of low doses on the biological system of man under medical and technical aspects. (DG)
