Pico is a scientific notation denoting a factor of 10 -12. The curie (Ci) unit is the activity of 1 gram of pure radium-226. What does pCi/L mean? PicoCuries per liter (pCi/L) is a unit for measuring radioactive concentrations. Ultimately the only way to tell if your home has a radon problem is to test for it. Elevated radon levels have been reported from all regions of the state. Locally the number of homes reporting elevated radon varies from a high of 7 out of 10 to a low of 1 out of 100. About 1 in 5 radon tests made in Florida are found to be elevated. What is the extent of radon problems in Florida? The department collects radon test reports from state certified radon testing companies. The average outdoor level is about 0.4 pCi/L. What is the average level of Radon found in homes in the U.S.? Based on a national residential radon survey completed in 1991, the average indoor radon level in the United States is about 1.3 picoCuries per liter (pCi/L). The amount of radon that escapes from the soil to enter the house depends on the suction created within the house, soil porosity, soil moisture, and the weather. Radon levels in the soil range from a few hundred to several thousand pCi/L (picoCuries per Liter). The amount of radon soil can produce depends on local geology and can vary from house to house. Since uranium is essentially everywhere in the earth's crust, radium-226 and radon-222 are present in almost all rock and all soil types. Radon-222 and its parent, radium-226, are part of the long decay chain for uranium-238. Radon-222 is the decay product of radium-226. The radon generated in rocks or water usually stays trapped in that material unless the rocks are fractured or the water is mixed with the air. Where does radon come from? Radon is constantly being generated by the radium in rocks, soil, water and materials derived from rocks and soils. Uranium is present in almost all rocks and soil and material derived from rocks. STEP FIVE: After inserting the tube add a bit of caulk where the tube enters the PVC pipe and where it enters the manometer to prevent it from slipping.What is radon? Radon is a colorless, odorless, tasteless, invisible and chemically inert gas that comes from the decay of radium in the soil. This prevents condensation from backing up into the manometer. Make sure to drill downward into the pipe. STEP FOUR: Drill another hole just above the manometer to insert tube into the pipe. STEP THREE: Slide the tube up or down until the oil reads 0. STEP TWO: Once you've found where you want to install the manometer screw it to the pipe using the enclosed screws. The important thing is that it be in a place where you can easily read it.Ĭontinue reading how to install your u-tube manometer below or watch this quick video. Generally, people choose to install the manometer in the basement or garage. STEP ONE: Find an easy to access spot below the radon fan to install the manometer. Installing a manometer on your radon mitigation system is pretty simple. Depending on the reading shown you may need higher- or lower-suction fan.įor more on radon fan selection see this page. So with just a quick glace you'll be able to reassure yourself if all is working correctly.Īlso, the level of pressure shown on your manometer will help you determine if you are using the correct radon fan. If your fan has stopped working the two sides of the u-tube will show the same amount of liquid. It's purpose is to be able to quickly reference if your radon fan is working. When correctly installed, the pressure created by your radon fan will cause one side of liquid in the u-tube to be higher than the other.Ī manometer does not read radon levels. A u-tube manometer contains a u shaped tube which is half full of liquid.
