Radon mitigation is the process of reducing the amount of radon in a home or building. There are two main approaches to reducing radon levels. The first is active soil depressurization, which is applicable to most buildings. This process involves putting a pipe or other device through the floor slab of the foundation and pushing the radon outside. The second approach uses mechanical ventilation. Both of these methods use suction points inserted into the soil or crushed rock beneath the foundation. They work together to reduce the amount of radon in a structure.
What is the most common method of radon mitigation?
Although radon mitigation systems are available to all homebuyers, it is still advisable to test the home for radon before purchasing it. Moreover, if a home has a radon mitigation system, most homebuyers consider it as a bonus. They want to protect the health of their family.
Once the mitigation system is installed, the homeowner must conduct periodic tests to check the level of radon. This should be done at least every ten years. The annual average radon level must be less than 2.0 pCi/L. If the radon level is high, a follow-up short-term test is recommended to ensure that the mitigation system is working effectively.
Another technique that can lower radon levels is using an air-to-air heat exchanger. This system is also known as an Energy Recovery Ventilator. It draws air from the air above the roof and disperses the radon quickly and harmlessly.
