Can you reduce radon by opening windows?

Author: Patsy Cartwright  |  Last update: Tuesday, December 7, 2021

As a temporary solution, however, you can reduce radon levels simply by opening windows. Opening windows improves air circulation and ventilation, helping move radon out of the house and mixing radon-free outside air with indoor air. Make sure all your basement windows are open.

How do you reduce radon in your home?

More Ways to Take Action
  1. Stop smoking and discourage smoking in your home. ...
  2. Increase air flow in your house by opening windows and using fans and vents to circulate air. ...
  3. Seal cracks in floors and walls with plaster, caulk, or other materials designed for this purpose.

What is the fastest way to get rid of radon?

Increase the airflow in your home: You can quickly and easily reduce the presence of radon gas by opening windows and using fans and vents to circulate fresh air. Note that this may make your home uncomfortable in very hot or very cold weather, but it may be a worthy tradeoff to reduce high levels of radon gas.

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.

Does radon dissipate in the air?

Outdoor radon exposure allows the concentration to dissipate into the atmosphere where it becomes less of a concern. Wells and springs, particularly in areas with large or multiple underground deposits of granite or limestone, can harbor dangerous levels of radon gas.

Will Opening Windows Lower Your Radon Levels?

Is it OK to live in a house with radon?

The EPA states, “Radon is a health hazard with a simple solution.” Once radon reduction measures are in place, home buyers need not worry about the quality of the air in the home. ... Since removing radon is relatively simple, your family will be safe in a home with a radon reduction system in place.

Does radon travel upstairs?

Radon is known to be a heavy gas. ... Please understand that the radon level can be significantly higher on an upper floor. Even if the radon level is lower on the first floor than say a basement radon level, it could be higher on the second floor. The only way to know is if you test.

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.

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 a dehumidifier help with 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.

Does finishing basement reduce radon levels?

Again, the only way to ensure you are removing radon from your home is with a mitigation system. Sealing the basement floor can help, but just sealing the cracks is unlikely to reduce your radon levels in the long term. Sealing all cracks and applying non-porous, thick epoxy coatings would be a better step.

How long does it take to mitigate a house with radon?

The radon removal process can be completed in one day. The typical amount of time to install a mitigation system is anywhere from 3-5 hours. The time will vary depending on the layout of the home and the difficulty of the job.

How long does it take for radon levels to drop?

Depending on the type of system, you'll want to wait at least 24 hours for radon levels to be lowered. The retest should be done within 30 days of the installation. Your radon contractor may perform their own test, but the EPA cautions against the mitigation contractor testing and evaluating their own work.

Can plants absorb radon?

Radon (222Rn) is a natural radioactive gas and the major radioactive contributor to human exposure. ... Plants are believed to be negligible in reducing airborne Rn. Here, we found epiphytic Tillandsia brachycaulos (Bromeliaceae) was effective in reducing airborne Rn via the leaves.

What are symptoms of radon exposure?

Possible symptoms include shortness of breath (difficulty breathing), a new or worsening cough, pain or tightness in the chest, hoarseness, or trouble swallowing. If you smoke and you know you've been exposed to high levels of radon, it's very important to quit smoking.

How long can you be exposed to radon?

If a person has been exposed to radon, 75% of the radon progeny in the lungs will become harmless lead particles after 44 years. When a particle damages a cell to make it cancerous, the onset of lung cancer takes at least five years, but often takes 15 to 25 years and even longer.

Does radon get worse in winter?

Since radon levels are likely to be higher during the winter you can expect the level to not rise much higher during the rest of the year. You are also most vulnerable to radon during the winter since you will be inside for much of it and breathing the same reheated, recirculated air.

Does humidity increase radon?

At a constant value of radon concentration, measured values have been found to increase linearly with increasing humidity, from 30% RH up to a value of ∼85% RH.

Does running furnace affect radon test?

Winter is a good time to test for radon because you are, in-most cases, measuring the worst case scenario for your home. With the hatches battened down and the furnace running, you are creating a scenario that can cause radon levels to be higher.

Are radon detectors accurate?

The National Radon Safety Board evaluates radon measurement devices in cooperation with the US Environmental Protection Agency. It requires that the individual relative error of each device be less than or equal to 20.0% and that the precision error of all devices be less than or equal to 20.0%.

Where should I put my radon detector?

Place a radon detector in the breathing zone, 2-6 feet above the floor, and away from drafts, exterior walls, sumps, drains, windows or doors. Radon may enter a building through cracks in the foundation or through sumps or drains and will usually be higher near these entry points.

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 sump pumps increase radon?

Can radon come from the sump pump or pit? Yes. Radon is a gas that enters your building from the soil beneath and around your house. These gases can enter your home through the footing drain tile that is connected to the sump pump in your basement.

Can radon tests tell if windows are open?

It is important to note that when testing a home for radon, the home must stay closed up. If any doors or windows to the outside are open, the test will be invalid.

Can radon be in upper floors?

Although radon concentrations on upper floors are typically lower than those in the basement, protracted exposure to radon concentrations between 74 and 148 Bq m3 also carries significant lung cancer risk(1416).
