Relation between the level of Radon in the underlay and in structures in Central Bohemia
KADLECOVÁ, Zdeňka
Radon is a natural radioactive gas originating from a radioactive transformation of uranium. It penetrates the Earths surface from the geologic subsoil and cumulates in buildings where it can reach hich concentrations. Building material is also a radon source in resident premises. Water is another radon source. It isimportant to realize that the building materials of a natural origin as well as water supplied to the houses also gain a higher volume radon activity from the geologic subsoil. Hence my thesis particularly focuses on the building subsoil. My thesis that the beologic subsoil isa significant radon source affecting the radon volume activity in the objects, however, a high radon index of the eoloic subsoil does not necessarily mean that a high radon volume activity values will be measured in the building situated on the subsoil. It very much depends on the technical condition of the object and the way of its ue.
