Do you have radon in your NY home? How much it costs to test, reduce levels of harmful gas

Do you have radon in your home? Unless you test for the harmful gas, it's impossible to know.

According to a recent study completed by the American Lung Association, 13.9% of radon test results in New York were at or above the action level recommended by the Environmental Protection Agency, ranking it 15th in the country.

Here's how to test for radon and what steps you should take if it's found in your home.

What is radon?

Radon is a radioactive gas that is odorless, tasteless and colorless. It is the leading cause of lung cancer in people who have never smoked and accounts for about 21,000 lung cancer deaths annually, according to the American Lung Association.

The only way to know if your home has high radon levels is to test it, the New York State Department of Health (NYSDOH) said. It enters buildings through cracks in the foundation, walls and joints as well as exposed soil, loose fitting pipes and water.

And the greatest risk for exposure is where you spend most of your time, which, typically, is inside your home.

When you should test your home for radon

The state DOH recommends testing for radon every five years and in these specific instances:

  • Every two years if you have a radon mitigation system to ensure it's working properly

  • When you are buying a home

  • After any major renovations

  • Within 30 days of installing a radon mitigation system

How to test for radon in your home

Radon test kits are available from the NYSDOH for $12.25 each. The cost includes the testing device, laboratory analysis and postage.

To request a radon test kit order form, email radon@health.ny.gov.

It is important your home is sealed up and all doors and windows leading outside are closed for 24 hours before and during the entire testing period to ensure an accurate test, the NYSDOH says. However, you can leave and re-enter your home during the test.

What to do if you have high radon levels in your home

If your home's test results show radon levels of 4 picocuries per liter of air (pCi/L) or higher, the NYSDOH recommends you take steps to mitigate the issue. You also may want to consider fixing it if your levels are between 2 and 4 pCi/L.

If your home has elevated levels of radon, the state says to contact a certified radon mitigator to help figure out your next steps.

Radon levels in most homes can be reduced to 2 pCi/L or below. Radon reduction systems can reduce radon levels by up to 99% and cost around $1,500 on average.
