Question: How Long Do You Have To Be Exposed To Radon For It To Be Harmful?

What does radon poisoning feel like?

Unlike with other gases like carbon monoxide, 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..

Is radon level of 8 bad?

In high radon areas, if the average level is higher than 4-8 pCi/liter (NCRP recommended level is 8 pCi/liter; EPA recommended level is 4 pCi/liter), appropriate action is advised. … However, no compelling evidence for increased cancer risks has yet been demonstrated from “acceptable” levels (< 4-8 pCi/liter).

What are the chances of getting cancer from radon?

The EPA estimates that radon exposure increases lung cancer risk eight to nine times in smokers compared with nonsmokers. Major scientific organizations believe that radon contributes to approximately 12% of lung cancers annually in the United States.

Do I need to worry about radon in my home?

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.

Can radon affect your brain?

Radon Gas has long been known to be the second most common cause of lung cancer after cigarette smoking. Studies have now revealed that it could also be associated with other cancers – including leukemia – and with brain diseases such as Alzheimer’s and Parkinson’s.

How do I reduce radon in my basement?

In homes that have a basement or a slab-on-grade foundation, radon is usually reduced by one of four types of soil suction: subslab suction, drain-tile suction, sump-hole suction, or block-wall suction.

Do granite countertops emit radon?

Granite, like any other stone, may contain veins of naturally occurring radioactive elements like uranium, thorium, and their radioactive decay products. … In addition to radon, naturally occurring radioactive elements in the granite can emit small amounts of beta and gamma radiation.

How accurate are radon tests?

Findings show radon tests of less than 90 days are imprecise up to 99 percent of the time. … A new study finds the only reliable way to measure exposure to radon gas is with a long-term testing kit, 90 or more days.

Is short term exposure to radon dangerous?

Not everyone exposed to elevated levels of radon will develop lung cancer, and the amount of time between exposure and the onset of the disease may be many years. Breathing radon does not cause any short-term health effects such as shortness of breath, coughing, headaches, or fever.

Is a radon level of 14 dangerous?

Radon levels are measured in picocuries per liter, or pCi/L. Levels of 4 pCi/L or higher are considered hazardous. Radon levels less than 4 pCi/L still pose a risk and in many cases can be reduced, although it is difficult to reduce levels below 2 pCi/L.

Can a house cause cancer?

Homes’ structural and safety features can increase risk for injuries, elevate blood lead levels, and exacerbate other conditions. Poor indoor air quality contributes to cancers, cardiovascular disease, asthma, and other illnesses.

Can opening windows 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.

What happens if you are exposed to radon?

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.

Are radon concerns overblown?

The early warnings may have been overblown, but research since has shown that lung cancer risk from the gas is real. Radon may not be tobacco, but health officials still rank it as the second-leading cause of lung cancer in the United States. …

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.
