Why do PGL devices provide both radon and radon decay products?
We believe that it is important to know both the potential risk as well as the actual risk. By knowing both, and if a decision is made not to reduce radon gas levels because the radon decay products are low, then the client understands that if the conditions that are causing the reduced radon decay products are changed (such as removal air filtration systems) then the actual risk from radon decay products could increase due to the presence of elevated radon gas.
