Quizplus · Accepted Answer

The most practical solutions to toxic levels of indoor radon involve both improved ventilation with fresh air and sealing off cracks in basement walls and foundations. Improved ventilation will help to dilute and remove radon gas from the indoor space, while sealing off cracks will prevent radon from entering the space in the first place. Bioremediation and increased cation exchange are not typically used to address indoor radon levels.
