How do you remove radon from your home?
In some cases, radon levels can be lowered by ventilating the crawlspace passively (without the use of a fan) 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 house.
Does finishing basement reduce radon levels?
Radon levels must be reduced even if you are not finishing your basement. Radon is a colorless gas and known carcinogen that can seep into a home from the soil and rock below. Because it comes from the ground, radon levels are usually highest in basements.
How long does it take to get rid of radon?
Generally speaking, it only takes one to three days to remove the radon from your home, and then it will need to be tested again. If levels are below the recommended threshold of 0.4 pCi/L, a radon mitigation system can be installed to prevent more radon from coming into your home.
Can radon be removed completely?
No level of radiation is considered completely safe, but it cannot be totally eliminated so governments around the world have set various action levels to provide guidance on when radon concentrations should be reduced.
Does 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 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.
How quickly can radon affect you?
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.
Should I worry about radon gas?
If we breath in high levels of radon over long periods of time this exposure can lead to damage to the sensitive cells of our lungs which increases the risk of lung cancer. Radon causes about 1,000 lung cancer deaths in the UK every year.
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.
How do I make my house safe from radon?
An active radon sump, fitted with a fan, is the most effective way to reduce indoor radon levels. Sumps work best under solid floors and under suspended floors if the ground is covered with concrete or a membrane. Occasionally, passive sumps without a fan may reduce radon levels.
When is radon the 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.
What percentage of homes have high radon?
Nearly one out of every 15 homes in the United States is estimated to have an elevated radon level (4 pCi/L or more).
Should I walk away from a house with radon?
If a potential buyer conducts a radon test and those levels come back high, the buyer has the right to walk away from the sale (nearly all do) and you’ll be obligated to disclose the radon to future buyers, reducing your appeal.
Is radon a deal breaker?
Radioactive gas doesn’t have to derail a home sale. Radon is a radioactive gas that emanates naturally from soil and rock. 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.
How bad is a radon level of 10?
Radon Risk If You Have Never Smoked
| Radon Level | If 1,000 people who never smoked were exposed to this level over a lifetime* |
|---|---|
| 10 pCi/L | About 18 people could get lung cancer |
| 8 pCi/L | About 15 people could get lung cancer |
| 4 pCi/L | About 7 people could get lung cancer |
| 2 pCi/L | About 4 person could get lung cancer |

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.
What is the average radon level in a home?
The average indoor radon level is estimated to be about 1.3 pCi/L, and about 0.4 pCi/L of radon is normally found in the outside air. The U.S. Congress has set a long-term goal that indoor radon levels be no more than outdoor levels.
Is 6 a high radon level?
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. The EPA estimates that a radon removal system costs about $1,200 for an average house.
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).
Is 20 a high radon level?
20 pCi/L 10 pCi/L 8 pCi/L 4 pCi/L 2 pCi/L 1.3 pCi/L 0.4 pCi/L If 1,000 people who smoked were exposed to this level over a lifetime*. . .
