How to Prevent Radon

Radon is a radioactive gas that occurs naturally and is produced by the breakdown of uranium in soil, rock and water. The air pressure within a home is typically lower than the air pressure in soil around the foundation of the home. This makes the home act as a vacuum that draws in radon through foundation cracks and other openings. High radon levels are the leading cause of lung cancer in non-smoking populations. The EPA and the Surgeon General recommend reducing the levels of radon in homes to prevent radon-related illnesses. Radon reduction techniques can reduce home radon levels by 99 percent.

• 1

  Determine the levels of radon in your home by hiring a qualified radon tester. Every state has a radon office that could be part of the state's department of health (for example, New York State) or the environmental protection agency. Contact your state's radon office in order to obtain a list of qualified radon testers.

  If test results indicate high radon levels, hire a certified radon mitigation contractor to reduce or eliminate the radon in your home. Contact private proficiency programs that certify radon professionals to access lists of privately-certified professionals in your area. An example of such a program is NEHA's national radon proficiency program. Choose the contractor by checking references. Ask for cost and time estimates. Determine if the contractor has inspected your home, and verified the radon test results prior to providing a bid.

• 3

  Ask the contractor to prepare a detailed contract prior to hiring him for the job. Review the contract with someone who has had similar work done, and ask about a warranty or service options. Sign the reviewed contract once you are satisfied, and schedule the contractor to install a radon reduction system.

  Check your contractor's work using the guidelines provided on the United States Environmental Protection Agency's radon Web site. Ask the contractor to thoroughly explain the radon reduction system, and describe the maintenance procedures.
