![]() The fan has just enough power to suck the radon out and keep it from gathering underneath the slab. The pipe extends all the way up above the roofline where the radon is released outside of your home. It uses an electrical vent fan and monitoring system to pump radon out through a vent pipe that is installed between the gravel of the sub-slab. It works well for these foundation types because radon has the tendency to accumulate under the concrete of the basement foundation, where small cracks can form and release the gas.Īn active sub-slab system uses suction to help keep radon from building up and seeping into your home. Our friends at Enduring Charm did a great job explaining the difference between the different types of systems (which we describe in detail below).Īctive sub-slab depressurization is a type of radon mitigation system that is mostly used on homes that have a basement on a gradient or a concrete slab basement. ![]() Then make a choice about how what kind of radon system your home needs. Your first order of business should be to caulk any cracks or openings in your foundation to reduce the amount of radon seeping into your home. The good news is that mitigating radon in your home with a radon mitigation system can be done without huge overhauls and without spending your children’s college fund. So, you did the radon test and the results came back high – what do you do now? You need to minimize the radon concentrations in your home and you can do that with a radon mitigation system. Long-term exposure can lead to a variety of health issues but you likely won’t have any symptoms of the radon exposure itself, only symptoms of serious illnesses such as cancer that occur after a long period of exposure. Radon tends to accumulate in places with inadequate ventilation. The truth of the matter is that radon is all around you and you’re probably breathing some in every day at a very low level. You can find a list of approved and licensed companies through your state’s environmental services agencies. This is recommended if you’re doing it as a part of a real estate transaction, either buying or selling.Ī professional will be able to provide a more accurate measurement for you, which may be something required by a mortgage lender, so make sure you look into that. You can call in a professional to do the radon readings for you instead of using a DIY kit. Just make sure to follow the directions closely to help you get the most accurate result. You can find these tests at most hardware stores to do yourself. If you’re in no hurry, then a long-term test will help to give you the best reading of your year-round radon average. If you need to get results fast, then a second short-term test is your answer.Follow up the short-term test with a long-term test to ensure the levels were read correctly the first time or perform another short-term test.If it detects radon levels of four picocuries per liter (pCi/L) or higher, then a follow-up test is needed. Have a short-term test completed over the course of two to three days or up to 90 days.The Environmental Protection Agency says to follow these steps when testing your home or office for radon: It utilizes alpha-track and electret ion chamber detectors over that time to measure the daily fluctuation of radon in the home. Long-term testing is taken for longer than 90 days.Short-term testing uses devices such as charcoal canisters, alpha-track detectors, and continuous monitors to take readings in your home, which will need to be kept as air-tight as possible for the duration of the test.There are two types of tests that can be done to detect radon: Since radon isn’t something you can smell, taste, or detect with the naked eye, you have to test the environment around you to know if it’s present. The EPA has found that one in every 15 houses has dangerously high levels of radon, so it’s worth the time and money to get your home (or potential home) tested. It can’t be seen or tasted, which is why it’s a good idea to regularly test your home. It’s then released into the air where unsuspecting homeowners can breathe it in, which can lead to serious health problems like cancer. When these elements release radon, it can enter the home through cracks in the foundation and even well water. These elements are found naturally in rock, water, and soil. Radon is a radioactive gas that is a byproduct of the breakdown of radioactive elements in the ground, such as thorium and uranium.
