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.

Data displayed on radonmap.com 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.
