Abstract

As the fundamental study of designing x-ray dosimeter , we measured the voltage variation of CdS, II-VI group semiconductor compound, by mAs variation. We obtained data in the condition of 50, 70 kVp, by increasing the tube current as 1, 2, 2.5, 3.2, 4, 5, 10, 20, 32, 50 and 80 mAs. The output time of CdS was increased as mAs increased. We figured the slope value of 50kVp as 0.0088 and 0.0081 of 70 kVp. And by regression method, we obtained the standard deviation of time, Y axis, at 50 and 70kVp as 0.00268 and 0.00333. The result of this ssudy is so important to design x-ray dosimeter.
