Radon placement guidelines

EPA protocol recommends placing the device in the lowest lived-in level of the home (for example, the basement if it is frequently used, otherwise the first floor). Test in a room used regularly, but not a kitchen or bathroom. Set the device at least 20 inches above the floor where it will not be disturbed, away from drafts, high heat, high humidity, and exterior walls.

For more information, see our radon testing and placement guide.

What are considered safe ranges for radon?

The U.S. EPA recommends fixing a home if the radon level is 4 pCi/L or more. Because there is no known safe level of radon exposure, the EPA also recommends considering mitigation for levels between 2 pCi/L and 4 pCi/L. The World Health Organization recommends remedial action when average concentrations are at or above 2.7 pCi/L (100 Bq/m³).

Interpreting varied radon test results

Radon levels naturally fluctuate by season and throughout the day. Temperature, weather, ventilation, and pressure differences can affect how soil gases enter a home. For the clearest understanding of exposure, continuous long-term monitoring is recommended. Place the device in the breathing zone, at least 20 inches above the floor and at least 3 feet (0.9 m) from an exterior wall. Do not place the device on stone hearths or countertops.

I have a spike in radon level. What causes this?

Check the measurement environment for nearby devices that may cause electromagnetic interference (EMI), such as a microwave or Wi-Fi router. The surface beneath the monitor can also affect readings; avoid placing the device on materials such as granite or other masonry surfaces.

At what radon level should I take action?

In the U.S., the EPA recommends taking action at 4 pCi/L or higher. There is no completely “safe” level of radon, and mitigation may also be considered at levels above 2 pCi/L.

Should I be concerned about radon in basements vs. upper floors?

Radon often enters a building from the ground, so basements and lower floors can have higher readings. Radon can still move throughout a home, so it is important to test frequently occupied living areas.

Why do radon levels fluctuate?

Common reasons include:

• Indoor/outdoor temperature differences
• Home sealing and insulation levels
• Ventilation and HVAC operation
• Weather such as snow, ice, or rain
• Changes in airflow and occupancy patterns
• Variations in atmospheric pressure
