Radon Map
The Technical Building Code (CTE DB-HS6) establishes radon exposure zones in Spain. Each municipality is classified according to its radon potential, determining the mandatory protection requirements for new constructions.
Consult the interactive map to find out the classification of your municipality and the required protection measures. Regardless of the zone, we always recommend taking a measurement to know the actual radon levels in your home or workplace.
