A vent pipe and fan are used to draw the radon from under the sheet and vent it to the out doors. This type of soil suction is called submembrane depressurization. Other radon reduction techniques that can be used in any type of house include sealing cracks in the foundation and natural ventilation . These methods are considered to be either temporary measures, or partial solutions to be used in combination with other methods. Compared to radon entering the home through soil, radon entering the home through water in most cases will be a small source of risk.
Radon gas can enter the home through well water.
It can be released into the air you breathe when water is used for showering and other household uses. Research suggests that swallowing water containing radon may pose some risk, too. After a radon reduction system has been installed, it is important to do a follow up radon test to determine the system s effectiveness. Having an independent tester perform the test, or conducting the test yourself, will eliminate any potential conflict of interest with the contractor. In addition, systems installed by a RCP contractor must include a warning device to alert you if the system stops working properly.
