Note that the vent through the roof does not cause water to spill down the pipe to the slab below; this is not a good thing for a variety of reasons. Some of the special diagnostic tests that should be performed before beginning the radon process include the soil type underneath the building, base design, and so on. However, it would be preferable and prudent to speak with the team in charge of the whole process and go over every detail with them.Do you want to learn more?

The presence of radon gas in soils across the United States is a growing source of concern. In a study conducted at the University of Iowa, radon was identified as the leading cause of lung cancer in non-smokers.
If you’re building a home in a high-risk area, you should consider installing a Radon Mitigation System early on. In certain areas, a test is now needed for any residential real-estate transaction, and this will most likely extend to cover most of the higher-risk areas. In any case, the small investment required to instal such a system is well worth it.
In a Basement or Slab-On-Grade Foundation, the device is installed by burying a perforated pipe underneath the slab in crushed rock and stubbing up a connector into the basement. A Passive Radon Mitigation System is created by venting this pipe to the outside (away from any windows in your house or your neighbours, preferably up through the roof).
If a test shows that levels are still too high after your house is finished, you may need to convert to an Active Radon Mitigation System, which involves installing a fan that runs continuously and creates low pressure under the slab, increasing the rate of gas evacuation. As a result, you’ll want to place the slab penetration in an easily accessible location with electricity to power the fan. Radon gas can be present in varying concentrations in almost any part of the world. The following link will take you to the EPA’s Radon Map Zone.
