Abstract
To evaluate the performance of cadmium sulfide as a multi-function X-ray dosimeter, we made an X-ray detector that was based on cadmium sulfide using evaporation technology, and measured its response to X-ray exposure. The voltages of cadmium sulfide were measured on the various X-ray tube potentials, X-ray tube currents and exposure times. The regression analysis of the voltage response of CdS on the tube-potential variation was y=0.0995x-0.1146 (
다기능 X-선 선량계로서의 cadmium sulfide의 X-선에 대한 특성을 평가하기 위해 cadmium sulfide 기반의 X-선 선량계를 진공 증착법을 사용하여 제작하였으며 X-선 노출에 따른 cadmium sulfide의 반응을 측정하였다. Cadmium sulfide의 X-선 관전압, 관전류, 조사시간에 따른 전압의 변화를 측정하여 이를 분석하였다. X-선의 관전압에 따른 cadmium sulfide의 반응을 회귀분석을 통해 통계처리 한 결과 y=0.0995x-0.1146 (
