Radon Reduction Diagram
Introduction: We think this diagram of a Radon reduction system is great! It presents an easily understood picture of a sub-slab depressurization system, which is for the purpose of reducing Radon in a home.
This is just one of the techniques for reducing Radon, as discussed in EPA's Guide.
The EPA also emphasizes that homeowners should also test again after it is fixed, to be sure that Radon levels have been reduced. Other advice is that if your living patterns change and you begin occupying a lower level of your home (such as a basement), you should retest your home on that level.
In addition, it is a good idea to retest your home sometime in the future to be sure Radon levels remain low. The EPA Guide posits several scenarios that warrant re-testing, from major renovations, such as converting an unfinished basement area into living space, to changes in home use, such as putting a rec. room in the basement.
When reading the EPA Guide, one can imagine testing and re-testing over the years, due to possible changes in the path that Radon gas may take. This may seem like too much to do, but a word to the wise should be sufficient.
