Radon is a noble gas originated from the radioactive decay chain of uranium or thorium. It emanates naturally from the soil and from some building materials, in particular in regions with soils containing granite or slate. A correlation has been established between the presence of high radon gas concentrations and the incidence of lung cancer. For instance, since February 2018, all EU countries under Directive 2013/59/Euratom, shall ensure radon levels lower than the reference concentration of 300 Bq/m–3 in workplaces. Although commercial radon detectors are available, most of them either are expensive or provide limited monitoring capabilities. This article presents a cost-effective IoT radon gas remote monitoring system able to measure radon concentration, trigger alerts to prevent dangerous situations, warn users about them, and activate mitigation devices (e.g., forced ventilation).
