What is the intent of conducting radon testing before renovations?

Conducting radon testing before renovations is essential for establishing a baseline for comparison. This baseline is crucial because it provides an initial measurement of radon levels in the environment before any construction work begins. Knowing the pre-renovation radon levels allows for better assessment of any changes that might occur as a result of the renovation.

By comparing post-renovation radon levels to the baseline, one can determine whether the renovation process has inadvertently increased the radon concentration in the building. This helps in ensuring that the safety of the occupants is maintained and allows for informed decisions regarding radon mitigation strategies if needed after the renovation.

While compliance with regulations and safety guidelines is important, the purpose of testing is primarily to understand the existing radon levels, thereby enabling effective monitoring and management after renovations. Conducting radon testing and having that baseline measurement is a critical practice to ensure the health and safety of those who will occupy the space after it has been modified.
