Natural radioactive element content of old granitoid rocks in the Great Hungarian Plain
Mean concentrations of radioactive elements of granitoid areas were determined for lithostratic and geodynamic units on the basis of analyses of natural radioactive element content of borehole samples from old granitoid rocks of crystalline basement of the Great Hungarian Plain.

| Tartalmi kivonat: | Mean concentrations of radioactive elements of granitoid areas were determined for lithostratic and geodynamic units on the basis of analyses of natural radioactive element content of borehole samples from old granitoid rocks of crystalline basement of the Great Hungarian Plain. Granitoids of the basement of the Great Hungarian Plain can be characterised by high U and Th content. Uranium content exceeds mean value for granites in the Earth for almost every granitoid formation of the Great Hungarian Plain; in some places it is three times higher. Radiological conditions of the given area comparing with that of Hungary as well as local features, accumulations, and leaching are discussed in summaries found at the end of subdivisions. Accumulation factor for radioactive elements of Codru Terrain is given for units (complex by complex), while that of Kunsag Terrain has been determined for subunits, too. |
