We plan on moving from New Jersey in Morris County to North Carolina somewhere in Wake county in the next few years. One of the things that has come up recently in Wake County is Radon levels, I do not know how comfortable I am with one of those things that vents the air outside of the house, I want something relatively radon free. So here it the map of North Carolina http://www.epa.gov/radon/zonemap/northcarolina.htm, well I know my friends have one of those suction vents for radon at their house in Pennsylvania by Allentown http://www.epa.gov/radon/zonemap/pennsylvania.htm and even though I was tested when I bought my home Morris County New Jersey is in the high area as well http://www.epa.gov/radon/zonemap/newjersey.htm. I guess I just have to buy a house in North Carolina that I have tested correctly and maybe more then once.
