Which mechanism is involved in radon transport due to differences in gas pressure?

The mechanism involved in radon transport due to differences in gas pressure is air pressure differences. When there are variations in pressure within the soil and the atmosphere, this can influence the movement of radon gas from the ground into buildings. Radon is a gas that can accumulate in enclosed spaces, particularly basements and lower levels of homes, if the pressure inside the structure is lower than the pressure in the surrounding soil. This pressure difference can create a vacuum effect, pulling radon-laden air from the soil into the indoor environment.

Understanding this concept is crucial for effective radon management and mitigation strategies, as it highlights the importance of monitoring and controlling indoor air pressure to reduce radon levels. Proper ventilation and air management can help minimize the ingress of radon gas into homes, addressing potential health risks associated with long-term exposure to radon.
