Technical and physical factor in medical exposure reduction were examined by calculating patient doses by the NDD calculation method from the conditions at radiographic regions in various in various institutions in Ibaraki prefecture based on fine surveys of radiography made every two years from 1985 to 1993,the average collection rate of which was 85.8%. 1) The differences in exposure dose by institutions were 30 to 75 times as to the same radiographic regions. 2) The average exposure dose in chest radiography for adults was 0.27mGy. 3) The rate of institutions using added filters was as low as about 40%. An added filter could reduce the exposure dose by about 40%. 4) In chest radiography for children, it is possible to reduce the exposure dose by 30% if a grid is not used. 5) The use of CR contributes largely to the exposure reduction in Guthmann and Martius radiographic method, but it doesn't always reduce the dose in chest or abdomen radiography in adults and children.
