Radon is the leading cause of lung cancer among nonsmokers. You can’t see, smell or taste radon, but it could be present at a dangerous level in your home. The only way to know if your home has high radon levels is to test it.

Radon test kits are available from the NYS Department of Health for $12.25 each. Cost includes testing device, laboratory analysis and postage. Email radon@health.ny.gov to request an order form.

Be sure to follow all test instructions. It very is important that the home is sealed up and all doors or windows to the outside are closed 24 hours before and during the entire testing period to ensure an accurate test. However, you can leave and re-enter your home during the test.

What is Radon?

Radon is a naturally occurring, radioactive gas found in soil and rock that gets into the air you breath. It seeps into buildings through cracks in the foundation, walls, and joints. It can get into any type of building--homes, offices, and schools. The greatest risk for exposure is where you spend most of your time – usually at home.

Major Radon Entry Routes

  1. Cracks in concrete slab
  2. Pores and cracks in concrete blocks
  3. Slab-footing joints
  4. Exposed soil, as in sump
  5. Cracks between poured concrete (slab) and blocks
  6. Loose fitting pipes
  7. Water

When to Test for Radon at Home

  • Every five years or every two years if you have a radon mitigation system to make sure it’s working properly.
  • When buying a home and after major renovations. During a real estate transaction, hire a certified radon measurement professional for testing. Be sure that the analysis of the radon test is performed by a company approved through the State's Environmental Laboratory Approval Program.
  • Within 30 days of installing a radon mitigation system.

Understanding Your Test Results

NYS DOH recommends fixing your home if the results of radon tests show levels of 4 picocuries per liter of air (pCi/L) or higher. With today's technology, radon levels in most homes can be reduced to 2 pCi/L or below. You also may want to consider fixing if the level is between 2 and 4 pCi/L.

Fix a Radon Problem

A radon reduction system can reduce radon levels in your home by up to 99% and average cost is about $1,500. If your home has elevated levels of radon, contact a certified radon mitigator. More information is available at the U.S. EPA's Consumer's Guide to Radon Reduction.

Building Homes To Keep Radon Out

New construction methods keep radon out of the home by sealing soil gas entry points, by preventing radon gas from entering the home and by venting to release radon gas outdoors. Installing a radon reduction system during construction is easier and less expensive than installing a system after the house is completed. Every new home should be tested, even if it was built to be radon resistant. If radon levels are still at or above 4 pCi/L, a certified mitigator may activate the system by installing a fan.

The American Association of Radon Scientists and Technicians and the American National Standards Institute (AARST/ANSI) have developed National Radon Standards for radon testing and mitigation. These are the currently accepted standards and supersede previous EPA standards for radon.

Find Regional Radon Training Centers for continuing education.

Radon testing firms and mitigators must report testing results to the DOH. View Title 10 NYCRR 16.130 Radon Testing and Reporting for laws and regulations.

For Radon Testing Firms/ELAP Certified Laboratories:

Part 16 of the New York State Sanitary Code requires the reporting of County or Zip Code and number of measurements. You are only required to report the name of the laboratory in cases where the laboratory report the radon results to DOH.

For Radon Mitigators:

Part 16 of the New York State Sanitary Code requires the reporting of County or Zip Code and number of mitigations.

Please email radon@health.ny.gov or call (518) 402-7556 to request the Excel spreadsheet template for reporting your data.

Completed reports can be submitted via:

  • Email to radon@health.ny.gov
  • U.S. Postal Service to:
    Center for Environmental Health
    Bureau of Environmental Radiation Protection

You can impact the health of New Yorkers by encouraging radon testing and mitigation, to help reduce the likelihood of radon induced lung cancer. Please consider:

  • Making radon educational materials available in your waiting room.
  • Displaying the "Have You Given Your Home a Radon Checkup?" poster.
  • Including a question about home radon testing on your patient intake form.
  • Scheduling a radon presentation for medical support staff by calling 518-402-7556 or by emailing radon@health.ny.gov.
  • Providing patients with information about how low-cost test kits may be obtained from the Radon Program..
  • Referring patients with more questions to the Radon Program.

The NYS Radon Task Force was established by Assembly Bill 10774A and Senate Bill 8845A in June 2018 to conduct a comprehensive study on the prevention of human exposure to radon and make recommendations to reduce and minimize exposure to New York State residents. The Council is chaired by the DOH.

Specific items to be addressed include:

  • The need for interagency coordination of public education and outreach and prevention programs
  • The need for training, education and possible licensing of radon services providers
  • Any other related information that the commissioner of health may deem necessary or relevant in carrying out such study of radon in indoor settings

A report of the findings and recommendations of the task force and any proposed legislation necessary to implement such findings shall be filed with the governor, the temporary president of the senate, the speaker of the assembly, the minority leader of the senate, and the minority leader of the assembly on or before November 1, 2022.
