Continuous Radon Monitors & Charcoal Canisters are used when testing for radon gas.
Radon is a colorless, odorless and tasteless naturally occurring radioactive gas that seeps from soil into the home through cracks and other opening in the foundation or walls in contact with the soil.
Exposure to radon causes lung cancer. The National Academy of Sciences estimates that radon causes between 15,000 - 22,000 lung cancer deaths each year in the U.S. Radon gas presents one of the highest health risks we face in our daily lives.
The New Jersey Department of Environmental Protection (NJDEP) recommends that all homeowners test their homes for radon.
Radon gas measurement is easy and should be considered by the buyer as part of any real estate transaction. At the time of the contract of sale, New Jersey law (N.J.A.C. 26:2D-73) requires that the seller provide the buyer with a copy of the results of any radon testing and information on any remediation that has been conducted in the home.
If you are testing a house that you are considering purchasing, you must use the services of a NJDEP certified radon tester. All professionals who perform radon tests or mitigations in New Jersey must be certified. They must demonstrate sufficient education and experience, take NJDEP approved courses in radon testing or mitigation techniques, and pass a written examination.
The NJDEP recommends taking steps to reduce radon levels if the gas concentration in the lowest liveable level of the house is four picocuries per liter (4 pCi/L) or more. A picocurie is a measure of radioactivity. This will markedly decrease the risk of developing lung cancer caused by radon exposure.
The most common method of radon gas remediation is sub-slab ventilation, which uses a fan to draw the radon gas out from below the slab or foundation, thereby preventing its entry into the house. Based on New Jersey data, this method is effective in almost every case in reducing radon gas levels to levels lower than 4 pCi/L. The cost is typically about $1,200, although it can range from $500 to $2,500.
