A Prediction Model and Method for Indoor Radon Concentration by A Radon Simulation Chamber. [PDF]
China CDC WklyThis study aimed to establish a new predictive model for indoor radon concentrations.We constructed a radon experimental model using prefabricated block walls and measured surface radon exhalation rates across multi-layer walls. The geometric parameters of various building envelopes (walls, floors, and roofs) were incorporated to calculate indoor radon
