How do you fix high radon in a basement?

In some cases, radon levels can be lowered by

ventilating the crawlspace passively

(without the use of a fan) 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 house.

Why does radon-222 build up in basements?

Radon gas accumulates in basements because

of low ventilation

. Heating and air-conditioning, natural air movement, the “stack effect,” as well as diffusion of radon gas through the floors and walls distribute radon throughout the house.

Is radon in basement dangerous?

Radon is a radioactive gas emitted naturally from the ground. However, when radon gets trapped indoors—after entering a home through joints in walls, basement floors, foundations and other openings—

Does finishing a basement reduce radon?

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.

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. … Running a window fan in a basement window reduces radon levels, but only if the fan blows air into the basement.

Do all basements have radon?

Basements aren’t the only place you can find radon

a new or worsening cough, pain or tightness in the chest, hoarseness, or trouble swallowing

Is radon worse in summer or winter?

To answer that question, yes, radon levels in a home tend to be

higher during the winter

. And those higher levels of radon gas can lead to an increased chance of lung cancer. While indoor radon gas levels are generally higher during winter, sometimes the summer can have higher indoor radon levels.

Is living in basement bad for health?

Some health risks to people who live in basements have been noted, for example

mold, radon, and risk of injury/death due to fire

. … Presence of mold can lead to “respiratory symptoms, respiratory infections, allergic rhinitis and asthma”, as well as personal belongings being contaminated by mold.

How do I make my house safe from radon?

An active radon sump

, fitted with a fan, is the most effective way to reduce indoor radon levels. Sumps work best under solid floors and under suspended floors if the ground is covered with concrete or a membrane. Occasionally, passive sumps without a fan may reduce radon levels.

Do Ceiling fans reduce radon?

One of the most effective systems for reducing the concentration of radon gas is a ceiling fan. These can generally be installed by the homeowner for a minimal cost. … For a

fifty-percent reduction

of radon gas, a ceiling fan can be used alone without the positive ion generator.
