Radon is a colorless, radioactive, tasteless and odorless noble gas that occurs naturally after the decomposition of uranium found in soil, rocks, and water. The major health effect of radon is increased risk of developing lung cancer. After smoking, radon is listed as the second major cause of developing lung cancer. This explains why it is important to have a radon gas mitigation system installed in your house, it is not a must that you insist on an expert to do the system because their are some other diy radon mitigation systems that you can implement therefore reducing the costs drastically. Here is a review of three major types of radon gas mitigation systems that you can install in your home.
1. Active suction
The active suction system comprises of electrical vent fan and monitoring system as well as a vent pipe that is placed between sub-slab gravel which stretches to the rooftop on the exterior of the house. When the fan is switched on, it gets enough power to prevent radon gas from building up under the home. The openings in the basement also get sealed which not only makes the vent of to be the only exit point for the accumulated sub-slab radon but also reduces the loss of conditioned air.
Active suction systems are limited to homes with concrete basement or basement on a gradient as there is a tendency for radon gas to build up underneath the concrete of the basement’s foundation. Eventually, cracks are formed in the concrete due to wear and tear making the accumulated gas to escape and enter the home.
2. Passive suction
This type of radon gas mitigation system is installed during the construction of the house. The house is usually built with different pressures in various parts to prevent the need for an automatic trigger for ventilation. The pressure difference is enough to make the air flow in a certain direction. A duct system is also installed to direct the radon away from the house.
The passive suction radon gas mitigation system is ideal for homes with less accumulation of radon. This system can also not recommended for old homes due to certain requirements.
3. Pressure system
This type of radon gas mitigation system involves a person who keeps the doors and windows in the bottom section of the house closed. This creates pressure difference that forces air into the home which in turn prevents radon gas from getting into the house through the foundation.
Though this is a least expensive method of preventing the buildup of radon gas, it places most of the responsibility on a person due to lack of hardware and failure to use technology.
