Should I Buy a House Portland with Radon Mitigation System
​Are you considering purchasing a home and unsure what a radon mitigation system is or whether the cost is worthwhile? You're in the correct place, then! In this article, you can find comprehensive information on radon mitigation systems.

What is a Radon Mitigation System?

​A radon mitigation system is a collection of procedures to lower or eliminate the amount of radon gas in a structure or house. The method extracts radon gas from the ground around the building's foundation and safely directs it elsewhere. A qualified radon contractor in Portland usually installs radon mitigation systems.

Types of Radon Mitigation Systems

To lower the quantities of radon gas in a building, a variety of radon mitigation methods are available:
​
  • Active Sub-Slab Depressurization System (ASD): This is the most common and effective technology, which includes generating a vacuum beneath the building's foundation to remove radon gas and securely exhaust it outdoors. Before it can enter the building, the radon gas is drawn from the soil by a fan that is part of the ASD system.
 
  • Passive Sub-Slab Depressurization System (PSD): This system is similar to the ASD system. However, it does not include a fan. Removing radon gas and expelling it outside depends on the normal pressure variations between the earth and the air inside the building.
 
  • Heat Recovery Ventilation (HRV) System: A heat exchanger is used in this system to move heat from the indoor to the outdoor air. It exhausts stale air from inside the structure and brings in fresh air from the outside. By mixing the radon gas with clean outdoor air, HRV systems can lower radon levels in the environment.
 
  • Natural Ventilation: With this method, you open windows and doors to let more air into a building. Although it is less effective than other systems and might not be the best option for places with high radon levels, this may assist lower radon levels.
​
The best radon mitigation system will rely on the unique characteristics of the building, including the type of foundation, the amount of radon gas present, and other elements. A trained radon mitigation specialist can decide the ideal system for a certain building.

Why Radon Mitigation is Important

​Radon is known to cause lung cancer; after smoking, it is the second most common cause of lung cancer in the US. Tests are the only way to determine if a building has too much radon. If the radon levels are too high, a radon mitigation system should be implemented to lower them and ensure the air quality inside is safe.

Understanding Radon and Its Dangers

​Radon is a radioactive gas made when uranium breaks down. It has no color or smell, so it can build up in buildings and make people inside sick.

Sources of Radon in Homes

Homes can get radon from:
​
  • Soil: Radon is in the soil and can get into homes through foundation cracks and holes.
 
  • Building Materials: Concrete and bricks, for example, can have trace levels of uranium that can cause the production of radon.
 
  • Water: Radon can dissolve and accumulate in water sources like wells and public water systems.
 
  • Natural gas: Natural gas can infiltrate dwellings and contains trace radon levels.
​
It's crucial to remember that not all homes have the same radon level, and even residences nearby can have significantly varying levels. You must have your home tested for radon to guarantee safe air quality.

Impact of Radon Exposure on Health

Radon exposure can result in serious health issues and even death. It is the second most typical cause of lung cancer in non-smokers and the most typical in smokers. The following are some ways that radon can be harmful to your health:
​
  • Lung cancer: Long-term exposure to high radon levels, particularly in smokers, can result in lung cancer. Radon is to blame for about 21,000 lung cancer deaths annually in the US.
 
  • Other cancers: Leukemia is one malignancy linked to radon exposure.
 
  • Breathing difficulties: Radon exposure can make breathing difficult and lead to coughing, wheezing, and other breathing difficulties.
​
The consequences of radon on your health depend on how sensitive you are to it, how long and how much you are exposed to it. But over time, exposure to radon at any level can increase the risk of developing lung cancer. As a result, radon testing is crucial, and if the results show high levels, action should be taken.

Guidelines for Safe Levels of Radon

  • Environmental Protection Agency (EPA) recommendations: The EPA advises testing homes and buildings for radon and taking action if levels exceed four pCi/L. (picocuries per liter). This threshold, believed to be the greatest acceptable exposure limit, is based on the typical annual amount of radon exposure.

  • WHO recommendations: According to the World Health Organization (WHO), the maximum amount of radon you should be exposed to is 2.7 pCi/L. This level is based on a more cautious approach to determining how harmful something is to health and considers potential long-term exposure.
​
  • Additional recommendations: The American Lung Association and the National Academy of Sciences both provide recommendations for how much radon is safe to be exposed to. The majority of these regulations align with what the EPA and WHO recommend.
​
Keep in mind that these guidelines are only recommendations to maintain the safety of the indoor air; they are not laws. Homeowners and property owners should take action to reduce radon levels if they exceed these recommendations. You'll be less likely to get lung cancer or experience other breathing issues.

Advantages of Radon Mitigation Systems

​
  • Active Soil Depressurization (ASD) Systems: This is the most prevalent method of radon removal. It entails installing a vent pipe in a structure's basement or crawl space. The fan, connected to the pipe next, draws the radon gas from the ground before it can reach the building.

  • Passive Radon Mitigation Systems: These systems are normally installed when a new building is constructed. A vapor barrier and vent pipes that allow radon gas to escape to the outside are examples of what they consist of.
    ​
  • Sealing Cracks and Openings: This method involves sealing all the cracks in the foundation, walls, and floors that could let radon gas into a building.
    ​

Factors Affecting the Effectiveness of Radon Mitigation Systems

  • System design and installation: How well the mitigation system works depends significantly on how it is designed and put together. Radon mitigation equipment lowers the radon level in the air inside to a safe level.

  • Type and condition of the foundation: The type of foundation and how well it is kept up can also affect how well the mitigation system works. For example, a crawlspace or basement foundation may need a different type of system than a concrete slab foundation.

  • Level of radon present: How well the mitigation system works depends on how much radon is in the home or building. If there is a lot of radon, you may need a more advanced system to eliminate it.

  • Proper placement and sealing system components: To get rid of radon gas effectively from a home or building, it's important to place and seal system parts like the suction point and pipes correctly. If something isn't put in place or sealed properly, it can leak and lose effectiveness.
​
When choosing and installing a radon mitigation system, it's essential to consider these things to ensure the system works to lower radon levels and improve the air quality inside.

Benefits of Proper Installation and Maintenance

If a radon mitigation system is set up and taken care of correctly, it can help in many ways, such as:
​
  • Reduced health risks: Lung cancer and other respiratory problems are less likely to happen if there is less radon in the air.

  • Improved indoor air quality: Radon mitigation systems reduce radon levels, help remove other harmful contaminants, and reduce moisture levels.

  • Increased property value: A radon mitigation system that is properly installed and cared for can raise the value of a home because it gives potential buyers a sense of safety and peace of mind.

Hiring a qualified professional to install and maintain the radon mitigation system is important to ensure you get these benefits. Maintenance and testing should also be done regularly to ensure the system works well and that radon levels stay low.

Evaluating the Effectiveness of Radon Mitigation Systems

​Radon mitigation systems are intended to lower radon levels in houses and other structures, but assessing their efficacy is crucial to ensure they're operating as intended. The first step in deciding whether a mitigation system is required is radon testing, and it's crucial to repeat the test after installation to ensure that the system is functioning properly.

The US Environmental Protection Agency (EPA) advises radon testing at least every two years and more frequently if levels have been high in the past or if the structure or its ventilation system has undergone any alterations. The lowest habitable level of the house, such as the basement or a first-floor room, should be chosen for testing.

Adherence to recognized testing protocols is crucial when assessing a radon mitigation system's efficacy. The Environmental Protection Agency (EPA) advises employing a qualified radon measurement expert or a radon measurement instrument that has passed the agency's testing procedure and is listed on its list.
​
The effectiveness of radon mitigation systems is likewise subject to standards. The most widely accepted standard is the ANSI/AARST Procedure for Radon Mitigation Systems in Existing Low-Rise Residential Buildings, which outlines specific steps for determining a radon mitigation system's efficacy.

Conclusion

Radon is a serious health hazard affecting indoor air quality in homes and buildings. Mitigation systems effectively reduce radon levels, but their effectiveness depends on proper installation and maintenance. It is important to test for radon regularly and evaluate the effectiveness of mitigation systems to ensure they're working properly.
