Quick Answer: How To Reduce Radon Exposure

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

How do you reduce radon levels in yourself?

Other radon reduction techniques that can be used in any type of home include: sealing, house or room pressurization, heat recovery ventilation and natural ventilation. Sealing cracks and other openings in the foundation is a basic part of most approaches to radon reduction.

Does ventilation reduce radon?

By opening windows, doors and vents on the lower floors, you increase the ventilation in your home. This increase in ventilation mixes outdoor air with the indoor air containing radon, and can result in reduced radon levels.

What are symptoms of radon poisoning?

A persistent cough could be a sign that you have radon poisoning. Persistent cough. Hoarseness. Wheezing. Shortness of breath. Coughing up blood. Chest pain. Frequent infections like bronchitis and pneumonia. Loss of appetite.

Can plants reduce radon?

Radon (222Rn) is a natural radioactive gas and the major radioactive contributor to human exposure. The present effective ways to control Rn contamination are ventilation and adsorption with activated carbon. Plants are believed to be negligible in reducing airborne Rn.

Does 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.

Can radon go through concrete?

Radon, soil gasses, and water vapor will easily pass through any openings, cracks, gaps, drains, or thin concrete (rat slabs) in the basement.

Where is radon most likely to accumulate in a home?

About one in every 15 homes is thought to have high levels of radon. The highest concentration of radon tends to be found in the basement or on the first floor.

Can you reverse radon exposure?

Unfortunately there is no cure for radon poisoning. Radon enters the body as in the form of tiny particles. These particles enter the lungs where they release alpha radiation that can damage lung cells and lead to lung cancer. The damage caused by the radiation cannot be reversed.

Does keeping windows open help with radon?

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. Homes tend to have lower air pressure than their surroundings, which draws radon into the basement.

Can radon in your home make you sick?

You won’t have symptoms of radon poisoning right away. Instead, health problems from the exposure, such as lung cancer, show up after many years. Lung cancer may start as a nagging cough, shortness of breath, or wheezing that doesn’t go away.

What type of soil has the most radon?

Granitic type soils present higher levels of radon gas. Non-granitic soils have traditionally been considered to have very low radon levels.

What type of soil is radon found in?

The U.S. Geological Survey explains that radon moves easily and quickly through porous soils, like sand and gravel, and slower through more solid soils, clay being one such example. Moisture has a lot to do with this.

Do trees absorb radon?

“Trees act as radon pumps, bringing the gas to the surface and releasing it to the atmosphere through transpiration — a process where water absorbed by the root system is evaporated into the atmosphere from leaves.

Does painting basement reduce radon?

Finished or Painted Basements Painted Walls – Sealing only the floor with RadonSeal can help. Much more radon tends to penetrate through the slab than through the walls, because radon gas is trapped underneath between the footings. Soil gas outside the basement walls can easily escape upwards to the atmosphere.

Do radon fans help with humidity?

The answer is, yes. Though, radon mitigation systems are designed to effectively reduce in home radon levels, there is a great byproduct of mitigation radon. One of the primary byproducts of a radon mitigation system is its ability to reduce moisture in your basement and/or overall humidity throughout your home.

Does humidity increase or decrease 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 sealing concrete reduce radon?

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.

Does air conditioning reduce radon?

A decrease in the mean value of radon and its attached progeny was found when AC was working. The mean value of radon equilibrium factor F was also lower when AC was working (0.49) than when it was off (0.61).

Where should you place a radon detector?

Detectors should be placed approximately 40 cm (16 inches) from an interior wall or approximately 50 cm (20 inches) from an exterior wall. The primary purpose of testing is to assess the level of radon to which occupants are exposed.
