How can Seller Lambert address concerns about radon in his home?

1. Only perform radon testing in winter.

2. Enhance airflow and ventilation to potentially lower radon levels.

3. Conduct radon testing as mandated by Health Canada.

4. Start testing on the top floor of a two-storey home.

5. Use chemical treatments to eliminate radon.

6. Focus on the basement area exclusively.

The correct answer is: Enhance airflow and ventilation to potentially lower radon levels.

Enhancing airflow and ventilation in a home is an effective strategy for addressing concerns about radon levels. Radon, a naturally occurring radioactive gas that can accumulate in homes, particularly in lower levels such as basements, can be mitigated by improving air circulation. By increasing ventilation, you can help to dilute the concentration of radon gas, thereby reducing its levels. This method can be a practical first step while considering more involved mitigation strategies if testing indicates that radon levels are above safe guidelines. Radon testing is important regardless of the season; therefore, solely performing tests in winter could miss fluctuations in radon concentrations that occur throughout the year. While Health Canada provides recommendations and guidelines regarding radon, conducting testing is not mandated. Starting testing on the top floor of a home may not yield accurate results, as radon typically accumulates in lower levels. Chemical treatments specific to radon are generally not the recognized approach for mitigation. Finally, focusing exclusively on the basement could overlook entry points and accumulation that may also occur on upper levels. Overall, improving ventilation is a proactive and effective way to address radon concerns in the home.
