Systems Can Remove Humidity
Radon mitigation systems can be a solution for indoor humidity control. Because sub-slab depressurization systems remove soil gasses from under the floor, they also remove large amounts of water vapor that could otherwise enter the basement or crawlspace. A radon mitigation system can dramatically effect the dampness, the smell, and the mold susceptibility of those areas.

Many radon mitigation customers have, over the years, indicated that they no longer need to use their basement dehumidifiers, or that the musty smell in the basement or crawlspace is gone. The radon system was acting as an indoor humidity control system.
EPA Sees Same Effect
A preliminary study by the EPA saw a dramatic dehumidification effect from the installation of a radon system. In their study, an average of 13-19 gallons a day of water was removed in their test. While your results may vary significantly, their results were significantly more humidity than is removed by an average portable dehumidifier. Click here for more info on this study.
Radon mitigation systems may cost more up front than dehumidifiers. However, they use much less electricity over the long term. They also are a quieter method of indoor humidity control, and are usually less conspicuous.
Subsoil situations vary and no specific humidity levels are guaranteed.
