Radon is a colorless, odorless, and tasteless substance that poses a health risk to humans. It is among the leading causes of lung cancer, second only to smoking. It can leak into homes through gaps in foundations or walls, necessitating homeowners to understand its concentration levels to protect themselves and their loved ones from its risks.
So, where is radon highest in house?
Let's investigate where radon can be found within a home and how to reduce high radon levels if this is an issue for your residence.
Where Can Radon Be Found in the Home?
Below are typical areas with elevated radon levels within homes.
1. Basements and Crawl Spaces
Basements and crawl spaces are some of the most likely spots where radon can be found, with levels typically reaching their highest point at the lowest part of any home or building. Testing in these spaces should be your starting point to ensuring safe levels. Radon in basements seeps through cracks in the foundation, walls, and floor of basements/crawl spaces, making them vulnerable to high radon gas emissions.
2. Lower Levels of Split-Level Homes
Split-level homes feature lower levels that are partially underground. These living areas may contain elevated radon levels, which further increases your exposure risk. Bedrooms or family rooms on these lower levels often function as living areas in these houses - further increasing your exposure risk to radon under house.
3. Rooms With Direct Contact with the Ground
Rooms built close to the ground, like sunrooms, tend to contain higher concentrations of radon than rooms that sit on an elevated platform, such as concrete slabs - another source of radon emissions. Furthermore, their walls often consist of glass which creates an enclosed greenhouse effect containing it within.
4. Areas With Poor Ventilation
Areas with inadequate ventilation, including bathrooms, laundry rooms, and kitchens, tend to have higher radon gas concentrations. Radon in homes can collect in these spaces if there is insufficient airflow between spaces making a dispersion of this gas more difficult.
5. Houses in Areas With Higher Radon Levels in the Soil
Homes situated in areas with higher soil radon concentrations tend to contain higher levels of radon inside. Since geological factors may contribute to soil radon variations, testing for radon should be performed at these locations regularly.
What Should Be Done If Your House Contains High Radon Levels?
Which area of the home will typically have the highest concentration of radon gas? If your home contains high radon levels, steps must be taken to minimize your exposure. The first step should be a comprehensive radon test conducted independently by an inspector or by purchasing a test kit from a hardware store. If the results show elevated radon levels at or above four pCi/L, then action should be taken and remediation efforts undertaken immediately.
Hiring a certified contractor specializing in mitigation is essential to solving your home's radon issues. Once at your property, the professional will assess it and recommend the most effective strategy for lowering its levels. This can include sealing cracks in the foundation or walls or installing an automated mitigation system.
Radon gas is a severe health hazard found throughout homes and buildings worldwide. To safeguard yourself and those you love from its risks, it's vital that you remain informed and take necessary precautions. By understanding where radon gas most frequently appears and testing for it in homes, you can take measures to reduce exposure. If your home may contain high levels of radon exposure, don't delay getting tested; an ounce of prevention is worth more than any potential cure for protecting against this deadly gas. Stay safe by staying informed!
