Understanding the Dangers and Taking Action
Â
What is Radon?
Radon is a colorless, odorless, and tasteless gas in the environment. It is formed by the breakdown of uranium in soil, rock, and water and can seep into homes through cracks and gaps in the foundation and through well water.
Health Risks of Exposure
Radon exposure is a significant health concern. Prolonged exposure to high levels can increase the risk of lung cancer, particularly in non-smokers. Moreover, it is the leading cause of lung cancer among non-smokers and is responsible for thousands of deaths each year. Other health effects may include respiratory issues and an increased risk of certain types of cancers.
Radon Levels in New York, Vermont, and Maryland
In New York, levels vary significantly, with a handful of counties reporting average indoor radon levels exceeding the EPA’s action level of 4 picocuries per liter (pCi/L). Vermont sees a similar pattern, with many homes testing above the recommended limit. It’s important to note that the Green Mountains region, in particular, has high potential due to its geology. Maryland also has regions of high potential, with several counties in the northern part of the state reporting average levels above the EPA’s action level. These levels underscore the importance of testing, regardless of state or county.
Testing and Measurement
Testing for radon is essential in determining if your home is at risk. Various testing methods are available, from short-term tests that provide a snapshot of levels to long-term tests that give a more accurate average over time. By conducting tests, you can assess the levels in your home and take appropriate measures to mitigate any risks.
Regulations in Construction Planning
When planning construction, it’s crucial to heed regulations to reduce the risk of radon accumulation in the building. These features, collectively called Radon Resistant New Construction (RRNC), involve simple and straightforward techniques that Architects and builders can integrate into their designs.

The EPA recommends using radon-resistant construction techniques in areas with high radon potential. Fundamental RRNC techniques include installing a gas-permeable layer under the slab or flooring system, such as a layer of clean gravel beneath the foundation, an appropriate plastic sheeting over this layer, a sealed and vented pipe running from the gas-permeable layer to the roof, and sealing and caulking all below-grade openings in the foundation and walls. Including a junction box in the attic for a fan can make adding a fan for active soil depressurization easier if higher levels are found post-construction.
While these measures may not entirely eliminate radon, they significantly reduce the potential for high-level accumulation. Incorporating these strategies during construction is more cost-effective and efficient than post-construction mitigation. Some states mandate these radon-resistant construction features in new buildings, particularly in high radon-risk zones. When working with Ardolino Design & Development, we consult local and national building codes and regulations for detailed guidance during our pre-design phase.
Mitigation Techniques
If elevated levels are detected at the site of your new or existing home, mitigation is necessary to reduce the concentration of radon gas. Different mitigation techniques for existing construction are available, including sub-slab depressurization, soil suction, and ventilation systems. Depending on the severity of the issue, we may hire a professional or implement a plan of action as part of our drawing set as mitigation strategies.
Conclusion
Radon is a silent threat that could be present in your home without your knowledge. Taking action to address radon is crucial for your health and the well-being of your loved ones. You can create a safer living environment by understanding the dangers of exposure, conducting regular testing, properly planning to meet local requirements, hiring a professional, and implementing effective mitigation techniques. Remember, knowledge is power, so spread the word about radon and encourage others to take action. Together, we can minimize the risks of exposure and create healthier homes for everyone.
