Radon Detection and Mitigation


Share post:

Radon is a naturally occurring gas that is the second leading cause of lung cancer after smoking. Radon is odorless, colorless, and tasteless, making it difficult to detect without specialized equipment. Radon gas can enter buildings through cracks in the foundation, walls, or floors, and can accumulate to dangerous levels if not properly mitigated.

Detection and mitigation are essential to ensuring that buildings are safe for occupants. In this article, we will explore the topic of radon detection and mitigation, including methods for detecting radon, the process of mitigating radon, and the importance of radon testing and mitigation.

Types of Radon Detection Devices

There are two types of radon detection devices: short-term and long-term. Short-term devices are designed to detect radon levels over a period of 2 to 7 days, while long-term devices can detect radon levels over a period of 90 days to one year. Short-term devices are often used for initial screening, while long-term devices are used for more accurate measurements.

Radon Testing

Radon testing involves the use of detection devices to measure the concentration of radon in the air. The EPA recommends that all homes be tested for radon, and testing should be done every two years. If the radon level is found to be above the recommended level, mitigation is necessary.

Radon Mitigation

Radon mitigation involves the use of techniques to reduce the level of radon in a building. One common method of mitigation is sub-slab depressurization, which involves the installation of a vent pipe and fan system beneath the building’s foundation to draw radon out of the soil and vent it outside.

DIY Radon Mitigation

DIY radon mitigation is not recommended, as it can be dangerous and ineffective. It is best to hire a professional radon mitigation contractor who is trained and certified in the installation of radon mitigation systems.

Choosing a Radon Mitigation Contractor

When choosing a radon mitigation contractor, it is important to select a contractor who is licensed and insured. It is also important to choose a contractor who is certified by the National Radon Proficiency Program or the National Radon Safety Board.

Cost of Radon Mitigation

The cost of radon mitigation can vary depending on the type of system that is installed and the size of the building. On average, the cost of mitigation ranges from $800 to $1500.

Radon-resistant New Construction

Radon-resistant new construction involves the installation of radon-resistant features during the construction of a new building. This can include the installation of a vapor barrier, a radon vent pipe, and a fan. Radon-resistant new construction is an effective way to prevent radon from entering a building.

Radon in Schools

Radon in schools is a growing concern, as children are more susceptible to the harmful effects of radon. The EPA recommends that all schools be tested for radon, and if the level is found to be above the recommended level, mitigation should be implemented.

Radon in Commercial Buildings

Radon can also be a problem in commercial buildings, such as offices and warehouses. Radon testing and mitigation should be conducted in all commercial buildings to ensure the safety of employees and customers.

Importance of Radon Testing and Mitigation

Radon testing and mitigation are essential to ensuring the safety of occupants in buildings. Radon is a silent killer, and it is important to take steps to prevent its harmful effects. Testing for radon is easy and inexpensive, and mitigation can be done quickly and effectively by a trained professional.


In conclusion, radon detection and mitigation are critical for maintaining a healthy indoor environment. The harmful effects of radon are well documented, and it is important to take proactive steps to ensure that buildings are safe for occupants. Hiring a professional radon specialist is the best way to mitigate the presence of radon in a building, as they have the expertise and specialized equipment necessary to accurately detect and mitigate radon.

When choosing a radon specialist, it is important to look for a contractor who is licensed, insured, and certified by a reputable organization. The cost of radon mitigation is a small price to pay for the peace of mind that comes with knowing that a building is safe for occupancy. Radon-resistant new construction is also an effective way to prevent the accumulation of radon in a building.

In conclusion, radon is a serious health hazard that should not be ignored. Testing for radon and implementing mitigation strategies is the best way to ensure that buildings are safe for occupants. By hiring a qualified radon specialist and taking preventative measures, we can all work towards creating a safer and healthier indoor environment.
