Space-Time Pattern Of Underground Radon Emission And The Influence Of Environmental Factors Using Sensor Networks, Sumya Tasnim

Geosciences Theses

Radon is the leading cause of lung cancer after smoking. There is a lack of information regarding underground radon concentrations at a local scale. This research assessed the underground radon emissions from 30 sensors from May 2022 to January 2023. This thesis utilized the emerging hotspot technique to identify the hotspots and coldspots of underground radon concentrations. It then evaluated their correlations with temperature, humidity, air pressure, CO₂, and volatile organic compound (VOC). The results indicated that the western side of the testbed and the warmer season had more hotspots than the rest of the area and colder …
