Study and experimental prototyping of a digital instrument for detection and acquisition with local monitoring on LCD of ionizing radiations using BG51 module and ESP32 microchip

Abstract

This paper presents a novel digital device for ionizing radiation detection in biomedical imaging media. It is designed and built using emerging technologies, in order to provide lower cost and high performance compared to existing biomedical instruments. The BG51 modular sensor is used as an ionizing radiation detector with corresponding pulses as output. Then, the ESP32 microchip acquires and digitalizes the ionizing radiation doses, and an associated 2.4-inch TFT LCD screen, is used as a hardware graphical monitor. A number of real time tests conducted in the laboratory, indicates that the ionizing radiation detection process, varies in the range [10μSv 2mSv]. In addition, the sample size with rate 30 samples per second, is approximately 25 000. Furthermore, the experimental results show the graph of ionizing radiation doses within a real environment where the proposed biomedical instrument is located.
