Cracks in concrete floors and basement walls are the most common entry points. The amount of entry points will vary depending on the construction of the building. There are numerous entry points for radon gas to enter a building. According to the American Cancer Society, radon is the number one cause of lung cancer amongst non-smokers. Lung cancer risks increase when either the concentration or length of exposure to radon gas increases. The health concern regarding breathing air that contains radon gas is the increased risk of developing lung cancer. Radon levels can accumulate within a building to a level that can cause health concerns. When radon gas comes into contact with a building foundation, it can enter the building. Once it reaches the earth’s surface, it becomes diluted into the atmosphere and is usually not a concern. Radon makes its way to the earth’s surface by travelling through small openings and cracks in the earth’s crust. Radon is therefore not isolated to certain areas of the world. Varying traces of uranium are found in the soils and rocks throughout the globe. Radon is a colorless, odorless gas that derives from the radioactive decay of uranium.
Additionally, this article will discuss how to properly select a radon fan from the pressure and flow test results. This test is also referred to as the communication test. This article will also discuss how to perform the pressure field extension test required for Active Soil Depressurization arrangements. The two most commonly used methods for radon mitigation include Active Soil Depressurization “ASD” and Passive Soil Depressurization “PSD”. Leaving a pipe open to precipitation may seem counterintuitive however, radon mitigation systems are designed to handle Minnesota weather.This article describes how to measure and mitigate radon levels within your home. People often ask why we don’t use rain caps on radon mitigation systems. So let’s look at a few flashing options and which one we recommend for radon mitigation. For example, if a roof flashing fails, a homeowner could end up with a leak. Which roof flashing is best? When exhausting a radon mitigation system through a roof, it is important to use quality materials. We strive to create effective and efficient systems, which includes asking ourselves, “How can we make it better?” Check out… WHAT IS OPTIMAL MITIGATION? What do we mean when we talk about optimal mitigation? Optimal mitigation refers to a mitigation system that reduces radon levels as much as possible with the lowest energy consumption possible. It’s a moving part, and it won’t last forever. Next, if you’ve checked all these things and the oil in the manometer is still equal on both sides it’s time to call a radon mitigation contractor. Is the small, clear tube that goes from the U-tube to the radon vent pipe still connected?.
It’s a visual gauge that tells you if your radon fan is running and at what static pressure.Īll active radon mitigation systems (this just means your radon system has a fan) are required to have a manometer installed so you can see if the radon fan is working. It is sometimes called a U-tube, how clever! The fluid is usually red, blue, or green. Check Your Manometerįirst thing’s first, a manometer is a U-shaped tube filled with fluid. In this post, we’ll help you determine if your radon fan is working.
