Elevated levels of radon gas can be found throughout New Hampshire, especially in the north, east, and southeastern portions. However, high radon levels can be found in any home regardless of location, so it's essential to have your home radon tested to determine the safety of your indoor air.
Although you may not be able to detect it with any of your human senses, the radon specialists at National Radon Defense can not only inspect your home's levels but also provide solutions for maintaining a healthy radon level in your New Hampshire home.

Comment: We tested the radon in the basement and it came out to 7 something long term and 8 something short term. So I'm looking to see an effective way to reduce that so we can maybe renovate to be a live able safe space
