Do most homes have radon?

Radon is a radioactive gas that has been found in homes all over the United States.

Nearly one out of every 15 homes in the United States is estimated to have an elevated radon level (4 pCi/L or more).

Elevated levels of radon gas have been found in homes in your state..

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 finishing a basement reduce radon?

Radon levels are above recommended EPA levels. Radon levels must be reduced even if you are not finishing your basement. … Because it comes from the ground, radon levels are usually highest in basements.

Does a dehumidifier help with radon?

Strictly speaking, a dehumidifier will not have much effect on the radon concentration in a home’s air. … Neither of them will have any effect on the radon concentration, but either or both of them will help to reduce the amount of radon daughter products entering your lungs with each breath.

What are the symptoms of radon in your home?

How much does radon remediation cost?

The cost for the installation of a radon mitigation system typically ranges between $2,500-4,000. The cost depends on how radon gas enters the home and moves within it, and each home is unique. Costs for mitigation of adjacent homes can vary significantly.

Is a radon level of 5 bad?

Safe radon levels. The best radon level measurement would be zero. … The average global outdoor radon level varies between 5-15 Bq/m3, equal to 0.135-0.405 pCi/L. For every 99.9 Bq/m3, or every 2.7 pCI/L increase in long term radon exposure, lung cancer risk rises 16%4.

Do radon levels change over years?

The EPA even recommends checking radon levels at least every two years as radon flow can increase over a timescale longer than one calendar year. This is to say, just as radon levels fluctuate within a calendar year, they also fluctuate as years pass.

Can you reduce radon by opening windows?

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.

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.

Is radon a deal breaker?

Radon is dangerous because it can cause lung cancer. Every year in the U.S. some 21,000 people die because of radon. Radon has a nickname that could easily scare away any potential home buyer: “The Silent Killer.” But there’s no need for radon to be a deal-breaker in any real estate transaction.

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.

What time of year is radon highest?

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.

Do air purifiers reduce radon?

Air Purifiers are great for mold, dust, allergies, bacteria and viruses, and odors, but many people do not know that they can also help with toxins, gases and chemicals such as radon. The most important type of air filter to reduce radon levels is an activated carbon filter.

How do I get rid of radon in my home?

Active subslab suction — also called subslab depressurization — is the most common and usually the most reliable radon reduction method. One or more suction pipes are inserted through the floor slab into the crushed rock or soil underneath. They also may be inserted below the concrete slab from outside the home.

Should I worry about radon gas?

Radon is considered to be the largest source of exposure to natural ionising radiation. Exposing sensitive bronchial cells to radon is known to cause damage in proportion to the number of cells exposed. Radon concentration is highest indoors, particularly in houses and small buildings.
