Radon Risk Map of the Bedrock at 1 : 500,000 scale. This map shows the prevailing radon index of different types of bedrock: 1. Low (Mesozoic and Tertiary sediments), 2. Intermediate (Quaternary sediments), 3. Medium ( Metamorphic rocks and Palaeozoic sediments), 4. High (Magmatic rocks, except for the Pre-Variscan granitoids – medium index), 5. Tectonic features, 6. Boundaries of regions
Data is intended for distribution of trace detectors in buildings and assessing categories of radon risk from map does not replace the duty of performing the measurement on the building site in accordance with the code SÚJB 307/2002 Sb. Bedrock radon index database contains data acquired with the support of the private companies associated in association called Radon risk.
