![]() Personally however, I would be concerned about any hazardous condition in the building that I spend the majority of my time, low-level or otherwise, especially when a permanent fix can be had for $700. You may choose to live in a house that has higher than recommended levels of a radioactive gas if you choose to do so. The fact that Canada's Action level is higher than the Action level in the United States is not a function of safety differences between Canadian radon and United States radon, but an expression of the level of political will toward addressing a hazardous condition.Īs a homeowner, what you ultimately decide to do is completely your decision. ![]() That probability goes up in direct correlation to the amount of time and amount of radon that you are exposed to. It should also be noted that ANY level of radon exposure correlates with an increased probability of causing lung cancer. The fact that it is over the US action level in that 48-hour period, is often indicative of a dangerous radon level, and usually indicates a need for remediation. The average indoor concentration in the UK is 20 Bq/m3. The radon test is a snapshot in time for the 48 hours or so that they ran the test for. Radon is measured in units of becquerels per cubic metre, Bq/m3 (the concentration of radioactivity in air). They are two separate issues with two separate fixes.Īlso it is important to note that radon levels vary over time so despite it being JUST over the US action level for the short time that it was being tested, a longer-term continuous radon test, of a month or longer may show that it is in fact averaging higher or lower then the tested level. According to EPA, the average radon level in American homes is about 1.3 pCi/L. Radon is naturally found in outdoor air at very low levels and some radon will always be in your indoor air. The working level of radon is in no way affected by humidity, or the entrance of water. Radon is measured in units of picocuries per liter (pCi/L) of air. The Radon Away 50017 Easy Read Manometer is an uncomplicated gauge that measures the suction level being produced by your radon fan. Radon is a radioactive gas that is a temporary byproduct of the decay of thorium and uranium. It doesn’t measure the radon levels in your home but simply reads/ monitors the negative pressure of your radon fan unit and does this constantly. Homes in summertime, with windows open and the whole house fan running, may have different overall levels than in wintertime when we batten down the hatches.You are. ![]() Keep in mind that radon levels in a house or building may change with the season. These are generally considered to be less reliable than continuous radon monitors, and may be better suited for long-term measuring. There are also passive devices available (inluding charcoal canisters, alpha-track detectors, and charcoal liquid scintillation devices) that are exposed to the air in a home or building for a specific amount of time and are then sent to a laboratory for analysis. These machines can observe spikes or dips in the radon level over a period of time (minimum of 48 hours), and typically include a device that reports if the machine has been removed or tampered with. Indoor air quality professionals measure radon levels with a continuous radon monitor. The EPA and equipment manufacturers recommend the testing of radon levels every two years for any house or building that has a radon mitigation system. This is what you want to see This means your system is down that means the system has no pressure, and the system is down. ![]() They measure the current vacuum pressure. They do not measure the current level of radon. Manometers are those u-shaped tubes coming out of the vent pipe, and they contain a liquid (sometimes blue, sometimes red). But what about those tubes and the numbers? We've all seen the sealed sump pump pits, the big fans, and the pipes. Now how about an explanation about radon and how the detectors are SUPPOSED to work, and how the blue fluid is supposed to register.would be very interested to know b/c in my condo on the first floor they put in these things and not one person can tell me if the levels should both be at zero or what.thanks. After all, this is National Radon Awareness Month. Your costs may vary depending on the size and design of your home and which radon reduction methods are needed. Most homes can be fixed for about the same cost as other common home repairs. I was asked a question about reading a radon system a few days ago, and it gave me the idea for a post. Some radon reduction systems can reduce radon levels in your home by up to 99 percent. Reading The Tube On A Radon Mitigation System ![]()
