How are Radon Levels Measured?
Radon gas is invisible, odorless and chemically inert, so it can't be detected without using special detection devices. Fortunately, radon detectors are commonly available throughout the U.S., Canada and most developed nations. The most common "passive" radon detectors can be purchased at hardware stores and home centers. These are typically placed in the house for at least several days, then sent to a lab where the radon level can be determined. More expensive "active" radon detectors are installed by professionals and monitor radon levels continuously.
If you need your house tested to determine the current radon level, a National Radon Defense contractor can help. Likewise, if you have already tested your radon levels and are seeking advice or installation on a radon Mitigation system, an NRD contractor can help with this as well. Call or contact us online.
Why do I have Elevated Radon Levels in My Home?
Most radon gas comes through the soil. So a house with a dirt crawl space has maximum radon exposure potential. But even houses with what would seem a tight concrete foundation can have high radon levels.
As a radioactive gas, radon can enter a home through cracks in the foundation floor and walls, through basement floor drains and through sump openings. Radon can also enter a home through holes made in the foundation walls for pipes and other utility lines. Radon gas that enters a home through the basement or crawl space has no difficulty moving to the upstairs and into living areas.
