The Oracle SDE database contains data on anomalous values of natural radioactivity, detected during surface prospecting of radioactive raw materials. It summarizes the databases "Radiometry - anomalous objects (RO)", "Radiometry - anomalous territory (ANUZ)" and "Radiometric exploration". These are radioecological data from approximately fifty years of work (1945-1994) of the former Czechoslovak Uranium Industry (ČSUP).

WMS service displays the Radiometric field map of the Czech Republic 1:500,000 (M. Manová, M. Matolín, 1995). This map was published by the Czech Geological Survey in the Atlas of map of the Czech Republic (GEOCR500) in 1998. Data on the gamma dose rate of rocks are based on regional and detailed airborne measurement of terrestrial radiation. The data of the map illustrate the regional distribution of natural radionuclides in rocks in the Czech Republic.

ArcGIS Server Service displays the Radiometric field map of the Czech Republic 1:500 000 (M. Manová, M. Matolín, 1995). This map was published by the Czech Geological Survey in the Atlas of map of Czech Republic (GEOCR500) in 1998. Data on the gamma dose rate of rocks are based on regional and detailed airborne measurement of terrestrial radiation. The data of the map illustrate the regional distribution of natural radionuclides in rocks and an above-average rock radioactivity in the Czech Republic.

Radiometric map of the Czech Republic (M. Manová, M. Matolín,1995) describes the natural radioactivity of the rocks on the Earth's surface. The radioactivity field is expressed in a batch a dose rate of gamma radiation of rocks 1 m above the Earth's surface. Map data defines the regions of low and high radioactivity.

This database contains depictions of areas explored for radioactive minerals by the former Czechoslovak Uranium Industry. The areas are indicated separately according to the following survey methods: surface or vehicle-born gamma survey, emanometry in test pits up to 1 m deep, combined emanometry and gamma survey in test pits up to 1 m deep, and combined emanometry and gamma survey in test pits 1-15 m deep.

This database contains data from radiometric survey. Radiometry means the measurement of the total gamma-ray activity of natural radioactive isotopes on the Earth’s surface, in the past the total exposure rate was measured. The first stage (measurement of exposure rate) was carried out in 1957-1973 using Geiger-Mueller counter; this survey covered the whole territory of the Czech Republic, measured data is stored in [µR/h]. Next stage started in 1976 when total gamma-ray activity was registered simultaneou...

Mapy radiometricky anomálních území (ANUZ) mají podat základní představu o radiační zátěži jednotlivých regionálních celků a zhodnotit příspěvek nalezených anomálních objektů ke zvýšení radiační zátěže. Ta je závislá zejména na primární koncentraci uranu, strukturně-tektonické stavbě území, hloubce zdroje, propustnosti zemin atd. Hodnocení proměřeného území z hlediska radiační zátěže je členěno do tří kategorií – vysoké, střední a nízké radioekologické zatížení.

Databáze radioaktivních objektů (RO) obsahuje dostupné údaje o anomálních objektech, zjištěných v průběhu bezmála padesátileté (1945-1994) průzkumné činnosti resortu ČSUP (nejsou zpracovány údaje z křídových sedimentů a objektů zjištěných v ložiskových vrtech). Údaje byly zpracovány z hlediska jejich vztahu ke geologické stavbě a jejich dopadu na životní prostředí. Databáze obsahuje geografické, archivní, geofyzikální, geologicko-strukturní, petrografické a mineralogické údaje o 16 203 objektech.

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).

INSPIRE Download Service (ATOM feed) provides access to the results of the mapping of radon index map in the Czech Republic at a scale of 1:50,000.
