M ETHODS THAT REDUCE RADON BY DILUTION
OR VENTILATION
Learning
Objectives
- Describe
approaches to ventilation.
- Define
air changes per hour.
Ventilation
Methods
- Increasing the fresh
air make-up to a building can dilute radon and other indoor air contaminants.
- Increasing air make-up
can reduce the negative pressures within a building, thereby decreasing the
radon entry.
Ventilation
Approaches
- Isolating and ventilating
substructures such as crawl spaces.
- Passively adding fresh
air make-up to living spaces.
- Actively adding fresh
air make-up to a living space, while removing interior air with some means
of recovery.
