Radon problems in schools are often remedied by increasing the ventilation. However, this will not necessarily remedy an IAQ problem. Some indoor pollution issues cannot be corrected by increasing ventilation. Increasing the ventilation in areas with high humidity or elevated outdoor air pollutants may, in fact, make an existing IAQ problem worse.
