Presumably, the radon is coming from the soil beneath the building in which case the usual remediation method is sub-slab depressurization.  Basically, you drill a 4" hole through the slab into the soil beneath, run a plastic pipe up to the roof where an exhaust fan sucks out the radon-contaminated atmosphere beneath the slab.  This stops the radon before it can enter the building itself.  Google the term "sub-slab depressurization" and you'll get lots of drawings, diagrams and descriptions.

Any competent radon remediation expert (guess the Yellow Pages are still useful!) can handle this.  For a home, it might run $1,000 or so, installed.

Good Morning,
We have a small room in our laboratory where radon gas buildup is an issue that interferes with our alpha detection equipment.
Anyone know of air filtration devices or any other solution that might help us eliminate this problem?
Thanks for your time and help.
