Radon is a naturally occurring gas that is found all over the world.
In the United States, the northern regions of the country are typically at highest risk, but no area of the country is radon-free.
Radon is an invisible, tasteless, odorless gas that's impossible to detect using human senses. It's possible for a building to have dangerously high radon gas levels, while the occupants remain completely unaware of the situation.
Fortunately, radon testing is possible through a simple, effective, do-it-yourself test. Professional radon testing services are also available.
Along with recruiting the best radon experts in the nation, the NRD network also offers simple, cost-effective radon test kits to homeowners who are interested in ensuring a healthier, safer home.

Radon exposure is the #2 cause of lung cancer in the United States -- second only to smoking. To date, estimates show that 15,000-22,000 lung cancer deaths occur in the USA annually.
Other symptoms of radon poisoning include a persistent cough that doesn't improve, difficulty breathing, chest pains, coughing up of blood, hoarseness, and recurring respiratory infections such as pneumonia or bronchitis.
Despite the danger that radon presents, many homeowners have not yet had their home tested for radon. Checking radon levels is easy and affordable, and should be done in every home.
