Description:
Active soil ventilation techniques have been tested in 26 block-wall basement houses in eastern Pennsylvania with significantly elevated indoor radon concentrations, generally above 740 Bq/m3, and the results indicate that radon levels can be reduced substantially often below the U.S. Environmental Protection Agency (EPA) guideline of 148 Bq/m3, if effective suction can be drawn on the soil underneath the concrete slabs of these houses. Such effective suction appears achievable when either: 1) the house has a complete loop of drain tile around its footings for water drainage purposes, and suction is drawn on that loop; or 2) a sufficient number of suction pipes can be inserted at the proper locations into the crushed rock or the soil underneath the slab.
