The Map Service (WMS Group) represents data from the radon measurements of the Saarland:The data are broken down by municipality and into four radon activity categories (0-99 Bq/m³; 100-299 Bq/m³; 300-1 000 Bq/m³; > 1 000 Bq/m³) and after the measurement time (short-term = up to several months; long-term = at least 1 year). The values in the categories are the number of measurements to date.
