Radon, a naturally occurring radioactive gas, poses health risks in enclosed spaces. Studies show nearly six percent of U.S. homes face high radon levels requiring mitigation. Traditional methods, though effective, can be costly and impractical for some dwellings. The Environmental Protection Agency (EPA) urges innovative mitigation strategies. Recent research suggests activated charcoal systems could be viable but require more case studies for EPA endorsement. Radon concentrations are higher near entry points. This study aims to determine if adsorption device placement affects radon distribution and concentration over time. This study, via numerical simulations, analyzes radon distribution in a ventilated room to optimize mitigation device placement. The effect of adsorption and radioactive decay is simulated along with a local sink. If placement impacts distribution, a multi-stage suction device with an activated charcoal filter is proposed. This approach could provide sustainable mitigation for low-income housing, improving public health by safeguarding vulnerable populations.
