Here is how you can reduce radon levels and beat a radon test; Seal all the entry points of radon into the home. Install vapor barrier. Avoid house depressurization. Use air to air heat exchangers. Install a radon mitigation system.
How do you lower radon levels before a 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 cheat on a radon test?
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.
Can a radon test be fooled?
What happens to a radon test result if the windows were opened, the test device moved, or there was any other evidence of tampering during the test? It’s simple: the test is voided and must be run again. No exceptions.
How do you skew a radon test?
Rain during the test period can skew test results—sometimes quite dramatically. This is because rain drives radon out of the ground, which results in a high radon level reading.
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.
How does opening windows affect a radon test?
Opening windows at the upper levels actually has the potential to increase radon levels during a short-term test. This is because the increased amount of dilution air that is brought into the house will typically be enough to offset any additional radon gas brought into the house.
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.
Are charcoal radon tests accurate?
Charcoal Radon Test Kits These tests are the cheapest and quickest options for measuring radon levels in your home, but they are also the least accurate because they are susceptible to spikes in radon levels and interference during shipping for lab tests.
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.
Does running a dehumidifier reduce radon?
Absolutely! Do continue to use the dehumidifier. It will help, not because the dehumidifier will remove radon, but it will remove very small particulates along with the moisture in the basement air.
Can anything affect a radon test?
Rain, thunderstorms and high wind can also have an affect on radon testing results. Radon readings have been known to go down when the outdoor wind speeds increase during periods of high humidity. When the seasons change such as fall to winter, radon testing can be affected.
Will dehumidifier affect radon test?
Test devices should not be within three feet of exterior doors. Close any air vents that would force air across the testing device. 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.
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.
How accurate are 2 day radon tests?
“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.
Does heat affect radon testing?
Temperature. Outside temperature can affect your radon levels. During the cold winter months, radon levels increase because of poor ventilation. Radon levels are lower when you can open your windows and allow outside air to circulate throughout your home.
What neutralizes radon?
Ceiling fans can reduce radon levels by 50%. If used along with positive ion generators, ceiling fans are capable of reducing radon levels by 90%. This is achieved by a phenomenon called plate-out, which neutralizes radio-active particles.
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.
Does fresh air lower radon levels?
An energy recovery ventilator reduces radon levels by adding fresh air and creating positive air pressure. Negative air pressure in lower levels of homes and building create a force that pulls soil gases including radon into the structure.
