Quick Answer: Does Radon Gas Rise Or Sink?

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..

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.

Does every home have radon?

Every building contains radon but the levels are usually low. In some parts of the country homes may have higher levels, and the chances of a higher level depend on the type of ground.

Does finishing basement reduce radon levels?

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 much does it cost to get rid of radon in your home?

Some radon reduction systems can reduce radon levels in your home by up to 99%. The cost of fixing a home generally ranges from $800 to $2500 (with an average cost of $1200). Your costs may vary depending on the size and design of your home and which radon reduction methods are needed.

Is radon gas heavier or lighter than air?

Radon gas is approximately 7.5 times heavier than air. It is however a noble gas with no chemical affinity but is easily influenced by air movements and pressure. In a house with forced air heating and cooling, radon gas can easily be distributed throughout the entire dwelling.

How long does radon stay in the air?

It can be found in all 50 states. Once produced, radon moves through the ground to the air above. Some remains below the surface and dissolves in water that collects and flows under the ground’s surface. Radon has a half-life of about four days – half of a given quantity of it breaks down every four days.

What time of year are radon levels 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.

Is a radon level of 5 bad?

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.

How long do you have to be exposed to radon for it to be harmful?

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.

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.

Is radon gas 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.

Can you sell a home with radon?

There are no laws that prevent you from selling a home with elevated radon, so you can do it. But, in certain states there are laws that require sellers to provide a radon disclosure in real estate documents. In some, the disclosure must also include known testing results and maintenance data for a mitigation system.

Does Radon only stay in the basement?

Because it is often found unexpectedly in basements, some people mistakenly believe that it only occurs in basements. … The fact that porous foundation walls allow radon gas to enter a home is no secret and with most basements containing a sump well, there are many access points from which radon can enter a 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.

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.

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.

How can I get a free radon test kit?

Free test kits are sometimes available from local or county health departments, or from state radon programs. The National Radon Program Services at Kansas State University has test kits available to purchase online at www.sosradon.org or call 1-800-SOS-RADON (1-800-767-7236).

Do dehumidifiers reduce 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.

How do you cheat a radon test?

Some of these methods for how to pass a radon test include:Open windows. By opening the windows, you increase fresh air circulation and reduce the concentration of radon in the home.Install basement vents. … Use fans. … Create exits. … Mitigation.
