Systematical Investigations of Cs - 137 Concentration in Soils in Bansko - Razlog Region

Systematical investigations of Cs‐137 concentration in soil in Bansko — Razlog region have been performed for the first time on a total area of about 40 km2. By means of high‐resolution gamma‐ray spectroscopy the radio‐nuclide content of soil samples has been determined. The Cs‐137 deposition density following the Chernobyl accident has been estimated and compared with results obtained in other countries. The additional dose rate caused by this fallout has been estimated, too.
