True or False: There is a strong correlation between low ventilation rates and high radon levels.

The assertion that there is a strong correlation between low ventilation rates and high radon levels is indeed true. Poor ventilation can trap radon gas inside structures, especially in basements and lower levels where radon is typically more concentrated due to its geological origin. Radon emanates from soil and rock beneath buildings, and without proper airflow to dilute or disperse this gas, higher concentrations can accumulate.

While ventilation rates are a key factor in determining indoor radon levels, they are not the sole consideration. Other variables, such as geographic location, soil composition, and building materials, can influence radon concentrations as well. Thus, it is more accurate to recognize that low ventilation rates often correlate with higher radon levels due to the lack of air exchange, but factors like those mentioned can also play significant roles. Therefore, a nuanced understanding is necessary when evaluating radon risks in indoor environments.
