초록
This research is the basical experiment for designing kVp meter using the photo-conductive property of Amorphous Selenium. At first, we charged the surface with A re discharge method, and changed the formed surface potential voltage by x-raying on that surface. As a result the variations of the surface charge increased by the rising kVp, while maintaining a constant exposure time and mA. We become to know that we can apply the photoconductive property of Amorphous Selenium in designing kVp meter.
