It seems like RADON testing is getting more popular in Georgia. The EPA certainly has a lot of information about it and I don't question whether it's a health problem or not. The research makes sense.
My concern is more about the proper way of testing and the companies administering the testing. There are several ways to test. There are kits from Home Depot that are inexpensive, but take proper placement in the home and then must be mailed away for the results. Time is the issue, especially if the data is needed in order to meet a real estate deadline.
Most inspectors use the electronic measuring devices. They are set up for about 48 hours in the home and then the data is downloaded and printed out. The placement of the device is critical. If the unit is on the floor or close to the floor, then the levels of radon will register higher than normal.
I had one inspector who set the machine up in the basement totally in the correct manner, turned out the light in the room and closed the door. He did not know that the light switch also was wired to the wall plug and so when he turned out the light, he turned off the machine. His results showed high levels of radon. (not sure how or why) We had it retested with TWO different mcahines, plugged into TWO DIFFERENT wall plugs and the results proved it was lower and at a safe level.
Many of the inspectors who buy these machines have had minimum training. I sugegst that you go the EPA website and read about radon BEFORE the home is inspected. That way you will have the right questions and know more about the process.
