Abstract (in english)
   The activity concentrations of Beryllium-7 (7Be), a naturally occurring radioisotope produced in the atmosphere, were measured in leaves of birch-trees, above-ground parts of grass, soil and rainwater in the mountain massive Kralicky Sneznik (the northeast of the Czech Republic, altitude about 750 m) in the years of 2005, 2006 and 2007. Dried and ground samples of the plants and soils, and water samples from wet deposition were used to determine the 7Be content using a semiconductor gamma spectrometer. The 7Be values ranged from 147.0 to 279.6 Bq kg_1, from 48.7 to 740.8 Bq kg_1, from 2.1 to 8.7 Bq kg_1, and from 0.6 to 1.9 Bq kg_1 in birch-tree leaves, grass samples, soils, and rainwater, respectively.
