Abstract (in english)
   The report summarizes the results of geological research according to the Czech Radon Programme, sources of radon in bedrock, methods and instruments, radon risk mapping, relationship between soil gas radon and indoor radon concentration.

   Radon 222Rn release from bedrock contributes substantially to the internal irradiation of the human body. The negative healt impact of unregulated lon-term exposure to radon has been proved in epidemiological studies. Because radon exhalation is generated by the radioactive decay from uranium-bearing rocks and soils, geological knowledge can contribute to definning the areas with enhanced radon exhalation from rocks and soils. In large plutonic rock bodies accessory minerals such as zircon or zirconium minerals in phonolites are considered to be some of the most intensive sources of radon A uniform method for soil gas radon measurements applied in the Czech Republic as well as soil data processing have enabled to construct maps of radon risk from bedrock in various scales. Different approaches to the constructing of the maps are discussed in the paper. The prediction of radon maps is illustrated using comparison of indoor radon measurements and bedrock radon data.
   Detailed radon risk maps primarily serve for locating the indoor radon detectors, which, consequently, leads to advancing the detection of existing dwellings, which have exceeded indoor radon guidance level and their mitigation
