How long does it take to get rid of radon?

one to three daysGenerally speaking, it only takes one to three days to remove the radon from your home, and then it will need to be tested again. If levels are below the recommended threshold of 0.4 pCi/L, a radon mitigation system can be installed to prevent more radon from coming into your home.

Where is Radon most commonly found?

Radon is present everywhere in the United States. Levels of the gas differ from state to state, but it is particularly high in North Dakota and Iowa. The U.S. Environmental Protection Agency’s Map of Radon Zones shows the potential for elevated radon levels for each county in the United States.

What are sources of radon in the home?

Radon is a radioactive gas that has been found in homes all over the United States. It comes from the natural breakdown of uranium in soil, rock, and water and gets into the air you breathe. Radon typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation.

Is radon found everywhere?

Radon is present in the air nearly everywhere, and everyone breathes in radon every day, according to the National Cancer Institute. At low levels, it is harmless. However, people who inhale high levels of radon are at an increased risk of developing lung cancer.

Is radon higher in summer or winter?

The higher amount in the winter is attributed to the observation that people normally keep their windows closed during the winter, allowing indoor radon concentrations to rise. The lower radon concentrations in the summer might occur because often open their windows, allowing low-radon outside air to enter the home.

Does opening a window reduce radon?

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 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.

What are the symptoms of radon in your home?

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.

Does finishing a basement reduce radon?

Radon mitigation in finished basements: Most newer homes would have a vapour barrier below the slab, though likely not well-sealed. Some homes will have none, but in either case, concrete in fairly good condition should provide enough of an air barrier to contain radon below it.

How quickly can radon affect you?

Radon gas can damage cells in your lungs, which can lead to cancer. Radon is responsible for about 21,000 lung cancer deaths each year in the United States, though it usually takes 5 to 25 years to develop.

Should I worry about radon?

The average home has about 1.3 pCi/L of radon. Such levels aren’t enough to worry about, but under the right conditions, they could make you sick. According to the EPA, a nonsmoker who was exposed to average levels of radon for a lifetime would have a 1 in 500 risk of developing lung cancer.

What does radon smell like?

Radon Has No Smell In truth, radon doesn’t smell like anything at all. It is a colorless, odorless, tasteless gas, which is what makes it all the more dangerous for you and your home. Only tests designed especially for radon can give you an accurate reading on the level of radon gas in your home.
