Radon: What is it and should you test for it during home inspection

Radon is a naturally occurring radioactive gas that is found in soil and rocks, and can seep into homes through cracks and gaps in the foundation. Radon is odorless and colorless, making it impossible to detect without specialized equipment. Exposure to high levels of radon over time can increase the risk of lung cancer, making it a serious concern for homeowners and potential buyers alike.

In real estate, radon testing is an essential component of the home inspection process. In fact, it is becoming increasingly common for home buyers to request radon testing as part of their inspection. A radon test involves the placement of a special device in the home to measure the levels of radon gas over a period of time, typically 48-72 hours. The test results will show whether or not the home has safe levels of radon.

In the United States, the Environmental Protection Agency (EPA) recommends that homes have radon levels no higher than 4 picocuries per liter (pCi/L). If a home has radon levels at or above this threshold, the EPA recommends that the homeowner take steps to reduce the levels of radon in the home.

Radon can be a particular concern in certain parts of the country, including Massachusetts. The state of Massachusetts has a higher-than-average incidence of radon in homes, making radon testing an essential component of the home buying and selling process.

If a home is found to have elevated levels of radon, the most common solution is to install a radon mitigation system. A radon mitigation system is a ventilation system that is designed to draw radon gas out of the home and vent it safely outside. These systems typically involve the installation of a fan and a series of pipes and vents that run from the basement or crawl space to the exterior of the home.

While the cost of radon mitigation can vary depending on the size of the home and the severity of the radon problem, it is generally considered a relatively low-cost solution compared to other home repairs. In addition, many homeowners find that the peace of mind that comes from knowing their home is safe from radon is well worth the investment.

In summary, radon testing is a critical component of the home inspection process for anyone buying or selling a home. Elevated levels of radon in the home can pose a serious health risk, but there are steps that homeowners can take to mitigate the problem. If you're considering buying or selling a home in Massachusetts, be sure to discuss radon testing with your real estate agent and make sure that the necessary precautions are taken to protect the health and safety of everyone involved.
