DETECTING AND ADDRESSING RADON CONTAMINATION IN THE HOME

Many homeowners are concerned about the possible presence of radon gas in their homes – and with good reason. The US Environmental Protection Agency reports that radon is the second leading cause of lung cancer in the US after smoking. Due to these concerns, more and more home buyers are considering radon detection to be a “must” when they are considering a particular property.

WHAT IS THE SOURCE OF RADON?

Radon is a naturally-occurring odorless, colorless, radioactive element that is formed by the ongoing decay of uranium in soil, rocks, sediments, and even well or ground water. While radon that escapes into the atmosphere is not harmful, dangerously high concentrations can build up indoors, exposing occupants to possible health risks.

HOW RADON ENTERS THE HOME

Radon gas can migrate into the home in several ways. Openings or cracks in basement walls or floors are common avenues.  Sumps, basement drains, and spaces between gas or water fittings can also allow radon into the structure. Elevated levels of radon can even be found in new homes.

HOW CAN HOME BUYERS FIND OUT ABOUT RADON IN A HOME THEY ARE CONSIDERING?

Many home inspectors will conduct radon inspections, usually as an add-on service to a standard inspection. The inspector will set up the testing equipment and report on the results once the proper measurement procedure is complete. It is important to realize that radon levels in any particular home can vary widely, even over the course of a few days. If an elevated level of radon is detected, steps can be taken to lessen the concentration inside the home.

REDUCING THE LEVELS OF RADON IN THE HOME

The EPA names several different radon reduction methods, including ventilation and installing a radon ventilation system that vents the gas above the roof. Sealing cracks in the foundation can increase the effectiveness of ventilation systems, but has not been shown to adequately reduce radon levels on its own. Professional mitigation services can provide recommendations for a home’s specific conditions.
