With the aim of detecting the presence of radionuclides in moss samples in
eastern Serbia, 129 samples of mosses were collected from 2000 to 2010 in the
region of the spas: Sokobanja, Banja Jošanica and Gamzigradska banja. The
data obtained show that 137Cs was present in all of the 129 samples from 3
sampling areas and 15 sampling localities and in 20 moss taxa. This indicates
that pollution with this radionuclide resulting from the Chernobyl accident
still exists. Changes in the average activity concentrations of 40K are
within measurement error limits, while for 137Cs changes in the average
activity concentrations are more noticeable, i.e. they have decreased with
time.
