Abstract

This research develops a low-cost demonstration kit that aims to facilitate understanding of the concept of determining the active region of an X-ray detector using a phototransistor. This demonstration kit provides a practical and effective tool for illustrating the basic principles of X-ray detection, focusing on the phototransistor as the main component. The research method includes designing an electronic circuit capable of converting changes in light received by a phototransistor into an electrical signal that can be measured. The interaction of X-rays with matter can produce fluorescence phenomena that emit visible light. This phenomenon is utilized to design a phototransistor-based X-ray detector by attaching a ZnS (Ag) fluorescent screen to the surface of a phototransistor arranged in a Darlington circuit. The measurement of the active area of the detector was carried out by collimating the x-ray beam from a 2000-watt Philips x-ray generator tube, 60 kV type PW 2215/20 NR 780026, and measuring the output voltage of the detector (Vout) every 1 mm the change in beam position horizontally or vertically. The experimental results show that the Darlington circuit can be applied to design phototransistor-based X-ray detectors. The detector's active area irradiated with x-rays was obtained at (3.5 ± 0.5) mm horizontally and (3.3 ± 0.5) mm in the vertical direction. The results validate the phototransistor's response to X-rays and provide a clear illustration of how the active region of the detector can be identified and measured.

Abstract

In this article, we discuss the experimental absorption of radioactive light radiation on various materials using Geiger Muller. Under certain conditions, Geiger Muller can be used to determine the absorption coefficient of a material. The radioactive rays observed in this experiment are gamma rays. Gamma rays are radioactive rays that have no charge so they cannot be deflected by magnetic or electric fields and have the greatest penetrating power. We made several important results on experimental studies of the absorption of gamma radiation passing through matter. Our results relate to the trend of the unexpected, measured intensity of radiation versus the thickness of the absorber, which confuses students and cannot be explained by many laboratory assistants. Finally, we believe that a distribution function is an effective tool for examining the contribution of the build-up factor in the Geiger Muller calculation of the measured radiation intensity.
