In 2005-2006, surface soil samples (0-15 cm) were collected from different
regions of Republic of Srpska (Banjaluka, Kupres, Glamoc, Ozren, Grahovo,
Manjaca, Samac, Novo Selo, Tursinovac, Skaric), in order to evaluate their
radioactivity. During the War lasted from 1992 to 1996, it is known that these
locations were imposed by NATO forces. Due to this reason the samples were taken
from these locations in order the presence of depleted uranium to be checked in
soil.  Concentrations of radionuclides in soil samples were determined by gama
spectrometry (HPGe detector, relative efficiency 23%). Results showed the
presence of natural radionuclides 226Ra, 232Th, 40K, 235U, 238U as well as the
produced radionuclide 137Cs (from the Chernobyl accident).
