Can ventilation reduce radon in offices or factories?

Yes — proper ventilation can significantly reduce radon levels in workplaces. By increasing airflow, you dilute the concentration of radon gas and reduce the pressure difference that pulls it indoors from the ground.

This can be achieved through mechanical ventilation systems, sub-floor extraction, or even improved natural ventilation in some cases. However, ventilation alone isn’t always enough — if radon levels are very high, a dedicated mitigation system such as a radon sump or active fan extraction is usually required.

Regular monitoring after ventilation upgrades ensures the improvements are working as intended.
