What is RADON:
Radon is a radioactive gas that comes from the breakdown of naturally occurring uranium in soil and rock. It is invisible, odorless and tasteless, and can only be detected by specialized tests.
Radon enters homes through openings that are in contact with the ground, such as cracks in the foundation, small openings around pipes, and sump pits. These trapped gases build up pressure. Air pressure inside homes is usually lower than the pressure in the soil. Therefore, the higher pressure under the building forces gases though floors and walls and into the building.
Radon may also be dissolved in water, particularly well water. After coming from a faucet, about one ten thousandth of the radon in water is typically released into the air. The more radon there is in the water, the more it can contribute to the indoor radon level.
Radon, like other radioactive materials, undergoes decay that forms decay products. Radon and its decay products release radioactive energy that can cause lung tissue damage.
Radon is the second leading cause of lung cancer in the United States.
While radon problems may be more common in some geographic areas, any home may have an elevated radon level. New and old homes, well-sealed and drafty homes, and homes with or without basements can have a problem. Homes below the third floor of a multi-family building are particularly at risk.

How do I know if I have a RADON issue in my home?
Testing your home for radon is easy. And homes with high radon levels of radon can be fixed (mitigated). The New Jersey Department of Environmental Protection (DEP) recommends that all homes be tested for radon. Homeowners can test for radon themselves or hire a New Jersey certified radon measurement company to perform the testing.
Any home can have a radon problem. Nearly 1 out of every 15 homes in the United States is estimated to have an elevated radon level (4 pCi/L or more). Elevated levels of radon gas have been found in many New Jersey homes.
What should I do if I have a radon issue?
A variety of methods can be used to reduce radon in homes. Sealing cracks and other openings in the foundation is a basic part of most approaches to radon reduction. In most cases, a system with a vent pipe(s) and fan(s) is used to reduce radon. These "sub-slab depressurization" systems (SSD) will remove radon gas from beneath your homes foundation and vent it safely outside. Similar systems can also be installed in homes with crawl space or slab-on-grade. These systems prevent radon gas from entering the home from below the concrete floor and from outside the foundation. These SSD systems have been proved to be economical & effective in reducing the level of radon gas in your home. The right system depends on the design of your home and other factors.
