Enhancing aerial mapping with gamma radiation detection: a study in UAE

Abstract This work presents a comprehensive study on the development of a sophisticated gamma radiation detection system based on a drone-mounted gamma scintillation detector tailored for aerial mapping and radiation surveillance, aimed at generating an environmental radioactivity map within the United Arab Emirates ( UAE ). The project incorporates careful assembly and calibration techniques that utilize four high-resolution crystals (two CeBr 3 and two Lanthanum Bromochloride crystals) to optimize detection sensitivity. Additionally, the study examines the effectiveness of a VETO system in improving the signal-to-noise ratio and reducing background. The detector system employs modern front-end and back-end electronics to digitize the signal at the outset of signal processing. The detector will be installed on a drone to facilitate thorough and effective surveys.
