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.

How long does it take to get sick from radon?

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. Early signs and symptoms of lung cancer may include: persistent cough.

What should you do if you are exposed to radon?

It is recommended that you inform your family physician of the radon exposure. If the physician recommends a chest x-ray to screen for lung cancer, or if it becomes medically necessary to perform a chest x-ray for other medical reasons, then this is an appropriate medical screening.

What happens if you live in a house with radon?

Radon is the second leading cause of lung cancer after cigarette smoking. If you smoke and live in a home with high radon levels, you increase your risk of developing lung cancer. Having your home tested is the only effective way to determine whether you and your family are at risk of high radon exposure.

How do you know if you have radon in your home?

The only way you can tell that you might have radon in your house is looking for the entryways. Finding cracks in your floor or walls might mean radon has made its way into your home, but there’s still no way to know for sure.

Can radon cause headaches?

The only known health effect of radon is an increased risk of lung cancer. Radon does not cause any warning symptoms like headaches, nausea, fatigue, or skin rashes. If you are suffering from those symptoms or other physical ailments, you should consult your physician.

What are the first signs of radon poisoning?

• Persistent cough.
• Hoarseness.
• Wheezing.
• Shortness of breath.
• Coughing up blood.
• Chest pain.
• Frequent infections like bronchitis and pneumonia.
• Loss of appetite.

Where should you place a 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.

Should I walk away from a house with radon?

Consumer Reports says you don’t have to. Radon-related deaths are due to exposure over the course of a lifetime. “You should definitely take it seriously but you really don’t need to walk away from the home.

How bad is radon exposure?

Being exposed to radon for a long period of time can lead to lung cancer. Radon gas in the air breaks down into tiny radioactive elements (radon progeny) that can lodge in the lining of the lungs, where they can give off radiation. This radiation can damage lung cells and eventually lead to lung cancer.

How accurate are radon tests?

“Short-term radon test kits are not effective in measuring radon gas exposure: Findings show radon tests of less than 90 days are imprecise up to 99 percent of the time.” ScienceDaily.

Do all houses have radon?

Remember all homes have radon gas in them. Where a high radon level is detected, it can be successfully lowered at a cost which is usually small when compared to the value of the house. When a high radon level is found, fixing the problem can help protect the value of your home.

Does radon cause dizziness?

Long-term radon exposure produces symptoms akin to those of lung cancer. Unlike carbon monoxide poisoning or exposure to other dangerous gases, you won’t notice symptoms like fatigue, headache, confusion or dizziness. That’s because radon gas decays rapidly, damaging the cells in your lungs as it breaks down.

Where is radon most commonly found?

Radon levels are usually higher in basements, cellars and living spaces in contact with the ground. However, considerable radon concentration can also be found above the ground floor. Radon concentrations vary considerably between adjacent buildings, as well as within a building from day to day and from hour to hour.

Should I be worried about radon?

Radon Is a Cancer‑Causing, Radioactive Gas But it still may be a problem in your home. When you breathe air containing radon, you increase your risk of getting lung cancer. In fact, the Surgeon General of the United States has warned that radon is the second leading cause of lung cancer in the United States today.

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.

Does radon show up in blood test?

There are no symptoms, signs, or laboratory tests that are specific to radon poisoning. There are specialized tests that can detect radon in your urine, bones, and blood, but the results of these tests only tell if you were recently exposed to radon.

Does radon affect memory?

But more recent research, performed at the University of North Dakota, indicates that radon may be a significant cause of two diseases of the brain: Alzheimer’s and Parkinson’s. The radon gas emitted from soil and rock is not a hazard in the open air.

What is radon poisoning?

Radon poisoning occurs when large amounts enter the body and cause harmful physical changes. It is a naturally occurring element that takes a gaseous form at standard temperatures and pressures and is one of the densest substances to remain a gas under normal circumstances.

How often should you test for radon?

The EPA recommends radon mitigation when levels exceed 4 pCi/L, and it is said that 50% of homes in Colorado have higher radon levels (see CDPHE radon map). The CDPHE recommends all homes — new and old — be tested every few years for radon.

Will radon go away?

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.

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.

How much does it cost to fix high radon levels in home?

Radon mitigation typically costs between $771 and $1,179, but the cost can reach as much as $3,000 for a large home or property with multiple foundations, according to HomeAdvisor.

What should you not do during a radon test?

Turn off all air moving devices during the test. This would include ceiling fans, dehumidifiers, regular fans, HEPA or any other kind of filtering device that moves air. Do not operate fireplaces or heating stoves during the test unless they are your main source of heat.

What should radon levels be in a house?

EPA recommends homes be fixed if the radon level is 4 pCi/L (picocurries per liter) or more. Because there is no known safe level of exposure to radon, EPA also recommends that Americans consider fixing their home for radon levels between 2 pCi/L and 4 pCi/L.

How does radon get in your house?

Radon is a radioactive gas. It comes from the natural decay of uranium that is found in nearly all soils. It typically moves up through the ground to the air above and into your home through cracks and other holes in the foundation. Your home traps radon inside, where it can build up.

Can radon get 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.

Can radon enter concrete?

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

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?

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.
