Radon tests detect either radon gas directly or the daughter products of radon’s radioactive decay. In the laboratory, the radioactive particles emitted from the charcoal are counted directly by a sodium iodide counter or converted to light in a liquid scintillation medium and counted in a scintillation detector.
How accurate is radon testing?
“Short-term radon test kits are not effective in measuring radon gas exposure: Findings show radon tests of less than 90 days are imprecise up to 99 percent of the time.” ScienceDaily.
What can affect a radon test?
A short term test is good at measuring your current radon levels, but these levels can fluctuate due to a number of factors, including: Barometric pressure. Temperature/Season. House construction. Rain soaked ground. HVAC system. Improper placement of the device.
How do you pass a radon test?
Some of these methods for how to pass a radon test include: Open windows. By opening the windows, you increase fresh air circulation and reduce the concentration of radon in the home. Install basement vents. Use fans. Create exits. Mitigation.
Can you test radon yourself?
You can do it yourself or hire someone to do it for you. from a hardware store. Or you can order one by calling 1-800-SOS-RADON (1-800-767-7236) or going to the National Radon Program Services website (http://sosradon.org/test-kits). Set up the testing device to check the air for radon.
How do open windows affect radon testing?
Don’t just open the windows However, opening the windows in your house will have little effect on your home’s radon levels. What’s more is that, even if radon levels are reduced with the opening of your windows, the levels will return to their higher rates once the windows are closed.
Will opening the basement windows before a radon test lower the results?
Unfortunately, no, opening the windows does not reduce radon. It is not a gas that will just permanently escape the home like smoke from something burning in the oven. The radon may seem to leave when the windows are open, but as soon as they are closed, it is back.
Will a dehumidifier reduce radon?
No, buying a dehumidifier will not make radon go away. Radon must be removed by a remediation method like active soil depressurization (ASD), which ironically has been shown to be even more effective at removing humidity from a home than a dehumidifier in the same EPA study.
Is radon higher after rain?
Wind and rain storms create the largest variables of radon levels when testing for radon gas. Rainier days tend to result in noticeably higher radon levels. This is because rainy days are often coupled with lower barometric pressure.
What causes radon to fluctuate?
Radon gas is a naturally-occurring radioactive gas found in the soil. Some weather events, like storms, typically cause radon levels in a home to rise. Other events, like heavy winds, can cause radon levels to either rise or fall. Essentially, weather events can cause your radon levels levels to either rise or fall.
Do people cheat on radon tests?
While it is understandable that most people selling their homes don’t want to pay for home repairs, radon gas isn’t something to mess around with. Tampering with a radon testing unit during a home sale is fraud, and can lead to lawsuits even years after you sell the home.
What time of year is radon highest?
The reason that radon levels in the home can be higher in the summer and winter is two-fold. During the winter, the air in your home tends to be much warmer than the outside air, and this temperature difference creates a vacuum within your home.
Does opening a window reduce radon?
Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Opening basement windows helps reduce negative air pressure, diluting radon with clean outdoor air.
Where is radon most commonly found?
Radon levels are usually higher in basements, cellars and living spaces in contact with the ground. However, considerable radon concentration can also be found above the ground floor. Radon concentrations vary considerably between adjacent buildings, as well as within a building from day to day and from hour to hour.
Is radon testing necessary?
When you breathe air containing radon, you increase your risk of getting lung cancer. If you smoke and your home has high radon levels, your risk of lung cancer is especially high. You Should Test for Radon. Testing is the only way to find out your home’s radon levels.
Which radon test kit is best?
The Best Radon Test Kit – 2022 The Best Radon Test Kit. Airthings Corentium Home Radon Test Kit. First Alert RD1 Radon Gas Test Kit. Health Metric Radon Test Kit. AccuStar Charcoal Radon Gas Test Kit. AirChek 43237-2 Charcoal Radon Test Kit. Kidde 442020 Radon Gas Detection Test Kit.
Will running a fan reduce radon?
In some cases, radon levels can be lowered by ventilating the crawlspace passively, or actively, with the use of a fan. Crawlspace ventilation may lower indoor radon levels both by reducing the home’s suction on the soil and by diluting the radon beneath the home.
Can you run ceiling fan during radon test?
Turn off all air moving devices during the test. This would include ceiling fans, dehumidifiers, regular fans, HEPA or any other kind of filtering device that moves air. Do not operate fireplaces or heating stoves during the test unless they are your main source of heat.
