what to know about radon gas
in your home


If radon gas is in your home, it's something you want to be aware of - and eradicate as soon as possible for your family's health and safety.

Typically, this odorless, colorless gas usually enters homes through the soil, or through cracks in the foundation or gaps in your home's flooring.

Why is detecting and eradicating radon important?

For starters, radon and lung cancer go hand in hand.

Trapped inside your home, radon gas can build to dangerous levels. 

Here's how to determine whether or not radon gas is present in your home.



Radon Gas is a Serious Environmental Threat

The second leading cause of lung cancer, radioactive radon is a serious environmental threat in many parts of the world.

Typically, this odorless element moves up through the soil and seeps into buildings through cracks and pores in the foundation and through gaps in floors.

Trapped inside, it can build to dangerous levels.

Check Your Home's Exposure with a Test Kit

You can check whether the gas is present in your home with a radon test kit (available online and at hardware stores).

An inexpensive test kit can put your mind at ease; or alert you to a danger that warrants professional eradication. These short-term tests remain in your home for anywhere from 2 to 90 days, depending on the device.

The most common short-term radon testers are charcoal canisters, alpha track, electric ion chamber, continuous monitors, and charcoal liquid scintillation detectors.

If testing shows your result is 4 pCi/L or higher of radon, take a follow-up test to be sure.  You can follow up with either a long-term test or a second short-term test:

  • For a better understanding of your year-round average radon level, take a long-term test.
  • If you need results quickly, take a second short-term test.


Take a Second Short-Term Radon Test if the First Result is Above Safe Levels

If your first short-term test result is more than twice EPA's 4 pCi/L action level, you should take a second short-term test immediately.

From there, once you've confirmed you have a problem, you can take steps toward remediation.

There are several proven methods to reduce radon in your home, but the one primarily used is a vent pipe system and fan, which pulls radon from beneath the house and vents it to the outside.

This system, known as a soil suction radon reduction system, does not require major changes to your home. Sealing foundation cracks and other openings makes this kind of system more effective and cost-efficient.

Check Your Water Supply

If there is radon in your water supply, it poses an inhalation risk and an ingestion risk. However, most of the risk from radon in water comes from gas released into the air when water is used for showering and other household purposes.

If you've tested the air in your home and found a radon problem, hire a certified radon professional to prevent infiltration.
