Radon Mitigation is needed whenever a radon test proves that radon levels are well above the recommended levels of (0.4 pCi/L) as the target radon level according to Radon Act 51 which was passed by Congress. At this point in time it is estimated that almost 67% of all homes have radon levels which are higher than this. The EPA has set an action level of 4 pCi/L, meaning that if your home tests at or above this level of radon you are supposed to take immediate corrective measures to reduce you and your family’s exposure to radon gas.
It is important to understand that just because a test is below the recommended action level set by the EPA, this does not mean that radon levels are safe. As a matter of fact, according to RADON.com, “It is estimated that a reduction of radon levels to below 2 pCi/L nationwide would likely reduce the yearly lung cancer deaths attributed to radon by 50%”, this means that the safest level of radon is technically 0.
While the safest level of radon is zero, it is important to note that avoiding radon is impossible. Walking and working outside in the sun, we are constantly exposing ourselves to radiation and our chances of developing skin cancer for example. Radon is quite simply another daily risk that we expose ourselves to like, “walking across the street”. It is important to reduce the amount of radon that we expose ourselves to.
After Testing for Radon
If after testing you have decided that it is time to mitigate, then you will need to decide whether or not you will contact a professional to help you mitigate the radon levels in your home or if you will try some of the work yourself. There are several excellent resources for you to decide.
Regardless of whether or not you will be performing the radon mitigation yourself or you will be hiring a radon mitiagation professional to help you improve the safety of your home, it is mission critical that you educate you and your family as to the dangers of radon and the most effective ways to reduce the radon levels of your home.
The basic process of radon mitigation is to alleviate or reduce the radon levels in your home by installing a radon mitigation system. The basic goal of the system is to dillute the amount of radon in your home by removing some or all radon from the home. As you have read, radon starts in the ground so the best place to address radon in most cases is by drilling a hole in the homes foundation and directing the air immediately adjacent to the foundation outside of the home and exhausting the air above the home's roof. The air needs to go from below the house out through the roof. The system will actually almost act as a vacuum from the foundation and then exhaust above the roofline.
The complete system will require running a solid exhaust line out through the foundation and up through your roof. It will also require the installation of a fan that will create the suction inside of the line to expel the radon. There are several very detailed guides as to how best install a radon mitigation system in your home. If you will be attempting to install the system yourself, here are a couple of solid guides on the process.
