A fan is installed on the exterior wall or in the garage attic area. One side of the fan is connected to a suction pipe installed in the sump pump cover or through the floor depending on the system which is being used. The exterior side of the fan is connected to an exhaust pipe which extends to above the roof line.
Sealing the sump pump cover and installing the suction pipe from the fan reduces the radon gas under the basement floor by using the drain tile.
When a sump Pump is not available or there is no drain tile the radon mitigation system is installed by drilling a hole in the basement floor to draw the gases out from under the floor. Sometime two holes will be needed because the soil conditions under the basement floor are to compacted. Radon testing is completed following the radon mitigation installation to insure the levels are below EPA guide line of 4 pCi/l.
Radon is a chemical element with symbol RN and atomic number 86. It is a radioactive, colors, odorless, tasteless gas. It is a natural decay product of uranium. Radon is the second leading cause of lung cancer behind smoking. The only way to find out the radon level is by testing. The level of radon gas hazard differs from location to location. No level of radon is safe so governments around the world set varies levels to provide guidance on when radon concentrations should be reduced while recognizing radon can not be totally eliminated. The EPA level is anything that is over 4 Picocuries per liter of air(pCi/l) should be mitigated. Testing can be done by purchasing a testing kit from your local hardware store or hire a professional that will use a Continuous radon meter which can give you a reading of every hour during the testing time.
Continuous Radon Monitor are used for the radon testing. Radon meters are calibrated annually and duplicate testing is done with meters setting 4 to 8 inches apart every 10 tests to insure meters are functioning properly. Radon meters are place no less than 20" from the floor and no more than 6' above the floor. Device should be 12' from the wall and 3' from any window or exit door. Device should be placed in the lowest occupancy level even if it is not finished at the time of the test but could be in the future. Closed house condition 12 hours before test is started and maintained throughout the testing time. Close house conditions means keeping doors closed except for normal entry and exit, and not operating fans or other machines which bring in air from the outside. Fans that are part of a radon reduction system or small exhaust fans operating for only short periods of time may run during the test. Short term test is a minimum of 48 hours with the long term test running for 91 days. A computer generated report is delivered after each radon test.
Radon testing and radon mitigation systems are done according to the standards set by the EPA and NRPP (National Radon Proficiency Program). Licensed for both testing and mitigation installations in Minnesota according to Minnesota Radon Awareness Act which took effect Jan 1, 2019.
