This tool determines the air volume needed from Heat Recovery Ventilators (HRV) to reduce radon concentration to a certain level. Heat Recovery Ventilators (HRV) are very useful as a second phase after Active Soil Depressurization (ASD) has reduced radon to near 4 pCi/L. They can reduce radon through dilution and […]

The equilibrium equation is a simple formula that defines the relationship between the concentration of radon in the air and the fraction of its decay products that remain suspended in the air. The pie diagram shown below is a useful tool for remembering and manipulating the equation (WL*3700/EF*Rn =1). Equilibrium […]
