Yellow areas mean that our goal to raise Radon awareness is working! People are often taking action to reduce their levels. Radon levels vary from home to home, so monitor yours to ensure it stays low.
Learn about the Airthings mission.
A significant amount of detectors are reporting warning levels in this area.
If your home’s detector reports between 49 - 99 Bq/m³ (1.4 -2.6 pCi/L), experiment with ventilation to reduce levels. Continuous monitoring will ensure the changes do not exacerbate the problem and keep those levels low.
A significant amount of detectors are reporting high Radon levels in this area.
If your home’s detector measures levels higher than 100 Bq/m³ (2.7 - 4 pCi/L) mitigation may be necessary.

Radon sensors from around the world show live radon data, broken down by location and anonymized. See yearly, monthly and approximate risk calculations in this easy-to-use, interactive map.
Press any square for detailed information regarding that location.
Data displayed on Radonmap is sourced from Airthings devices and updated inline with user syncing. All data is encrypted and privacy protected to ensure maximum user safety and device locations are concealed and grouped for ambiguity.
The Radon risk area is determined by an average level of the indoor air data gathered, but does not provide definitive results for each home and therefore continuous monitoring is recommended.
The map is intended to give only an indication of region-based air quality levels across the world based on Airthings device data. Precise levels will vary from home to home, so measuring individual Radon levels is always recommended.
Radonmap uses Airthings sensors from around the world to show live radon levels, broken down by location and anonymized. See the yearly and monthly approximate risk calculations in this easy-to-use, interactive map.
Click on any square to get more details on the radon levels in that area. You will find a graph and the risk level in that area. Data is sourced from Airthings Wave devices and is encrypted and privacy protected.
White space on the map means that there is no available data in this area. However, it does not mean there is no radon! Start monitoring today, to find out if you have problems with radon.
Airthings creates the world’s leading radon and indoor air quality monitors for homeowners, businesses and radon professionals. Started in 2008 by CERN particle physicists, Airthings is on a mission to empower the world to breathe better. Learn more.
