Due to the paucity of data on separate spatial distribution of cosmogenic Be-7 radionuclide activities in forest soil layers, a spatial study was performed in Mount Ida (Kazdagi)/Edremit, Turkey. In this study, it was aimed to examine the Be-7 spatial variability and depth distribution in the surface soil layers. The 7Be activity concentrations were determined by HPGe gamma spectrometry system and the distributions of Be-7 activities in the O-L and O-F + O-H horizons throughout the region were mapped separately. Activity concentrations of Be-7 in O-L horizons and O-F+O-H horizons varied as 35 +/- 23-701 +/- 40 Bq kg(-1) and 0.96 +/- 0.63-197 +/- 11 Bq kg(-1), respectively. 7Be inventories (0.20 +/- 0.06-5.69 +/- 0.75 kBq m(-2)) in the study area were relatively higher when compared with the other regions of the world. Be-7 inventories increased with altitude, slope and the thickness of the humus layer in some of the investigated area. Average 7Be activity level in deciduous forest stand type was significantly higher than that for coniferous and mixed stand types. Our limited data could not provide a latitudinal distribution pattern of Be-7 soil inventory or precipitation dependence and further investigation is needed.
