Question: What Is Considered Long Term Radon Exposure?

What time of year is radon highest?

Radon levels can vary by season, with the highest levels typically occurring during the months that we heat our homes.

That means that even if your home’s radon was below the EPA’s suggested action level of 4.0 picocuries per liter of air during the warmer months, it could be above that level during the winter..

How much exposure to radon is harmful?

The U.S. Environmental Protection Agency (EPA) recommends radon levels at home below 148 Bq/m3. According to the WHO, “lung cancer risk rises 16 % per 100 Bq/m3 increase in radon exposure”.

How long do you need to be exposed to radon for it to be dangerous?

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.

What are the symptoms of radon exposure?

If you think you’ve been exposed 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.

Should I worry about radon gas?

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. At 4 pCi/L, the risk jumps to about 3.5 in 500.

What health problems does radon cause?

When you breathe in radon, radioactive particles from radon gas can get trapped in your lungs. Over time, these radioactive particles increase the risk of lung cancer. It may take years before health problems appear. Radon is the second leading cause of lung cancer after cigarette smoking.

Is radon really a concern?

Now, according to the EPA, the WHO, and many other big public health organizations, radon is second only to cigarette smoking as a leading cause for lung cancer. The EPA says radon gas causes 21,000 deaths every year. … But critics say scientists can only prove that radon is carcinogenic at high doses.

What is long term 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.

Is short term exposure to radon dangerous?

Breathing radon does not cause any short-term health effects such as shortness of breath, coughing, headaches, or fever. … Research suggests that swallowing water with high radon levels may pose risks, too, although risks from drinking water containing radon are much lower than those from breathing air containing radon.

Should I not buy a house with radon?

Radon can seep into any home that is in contact with the ground. It is undetectable unless you perform a radon test. It is the second leading cause of lung cancer and according to the EPA and CDC, it kills more than 20,000 annually. It is not something you want in the home you are buying.

Is it hard to sell a house with radon?

Fortunately, it’s not hard to sell a house with radon, provided that you alert potential buyers and mitigate the problem, say Brian Thomas, a top real estate agent in the Denver, Colorado area, with 16 years of experience. “For as much fear and uncertainty as radon causes, there’s an easy fix.”

Is radon a scare tactic?

The radon scare was set off because of lung cancer in early uranium miners. … Residential radon is harmless. Exposure limits set by EPA with LNT theory also impair progress in medicine and nuclear power. EPA rules ignore science, biology, and observed low-level radiation health effects.

How long does it take to get cancer from radon exposure?

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.

How do you get rid of radon?

There’s no single method that fits all radon removal system needs. Common techniques include: Sub-slab depressurization, where suction pipes are inserted through the floor or concrete slab into the concrete slab below the home. A radon vent fan then draws out the radon gas and releases it into the air outside.

Can radon cause mental illness?

Mental health experts generally agree that people dealing with the presence of high levels of radon in their homes are likely to have related psychological problems if they are prone to other forms of stress.

Can opening windows 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. … Opening basement windows helps reduce negative air pressure, diluting radon with clean outdoor air.

What is considered long term exposure?

Long-term exposure is called chronic exposure. Either may cause health effects. Acute exposure is a short contact with a chemical. It may last a few seconds or a few hours. … Chronic exposure is continuous or repeated contact with a toxic substance over a long period of time (months or years).

Does Radon make you tired?

The more uranium there is, the more radon there is. … That makes radon the second leading cause of lung cancer after smoking. But even minor symptoms like headaches, feeling unusually tired, itching or burning eyes, irritated skin, nasal congestion, a dry throat or nausea could be due to your home’s indoor air quality.

How bad is a radon level of 5?

The best radon level measurement would be zero. Unfortunately, that’s not possible. 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 percent.

Does radon have a smell?

Radon is a radioactive gas with no taste, smell or color. This means the human senses alone cannot detect it. That is why, although radon was discovered in 1899 and even back in 1530 Paracelsus noticed some health effects in miners, regulation and radon’s connection to lung cancer are fairly new.

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.
