Radon index map 1 : 50,000 (GEOCR50)

In the database of the "Radon Risk Association“ the measurements of radon in bedrock from the whole area of the Czech Republic are stored. Maps of radon index at a scale of 1:50,000 have been compiled using statistical procedures to process the measurements so that the areas defined by the vectorized boundaries of the geological units can be classified using colours to indicate the prevailing radon index for bedrock and quaternary sediments (low, medium, high index).
