If a home has an area of more than 2,000 sq ft, what is recommended?

The recommendation for additional testing in a home that has an area of more than 2,000 square feet stems from the need to obtain a more accurate and representative assessment of radon levels throughout the entire space. Larger homes can have variances in radon concentrations due to factors such as airflow, building materials, and the configuration of the home, which can influence how radon accumulates and disperses.

Conducting additional testing allows for a comprehensive evaluation by checking multiple locations within the home or by using longer-term testing strategies. This approach helps ensure that all areas of the home are adequately assessed, reducing the chance that elevated radon levels go undetected in less frequented spaces.

Shorter testing periods, measurement recalibration, or installing higher efficiency devices may not specifically address the unique challenge posed by larger homes where radon mitigation might be necessary in varying degrees across different areas. Therefore, additional testing is vital in ensuring that radon mitigation efforts are based on thorough and accurate data.
