In this work we present the activity concentrations of natural radionuclides
40K, 226Ra, 232Th, 238U and 7Be in mosses. One hundred and sixty-seven moss
samples were collected between 2001 and 2012 from the territory of the
Sokobanja, Banja Jošanica and Gamzigradska Banja spas. They were classified
into 23 species. The activity concentrations (Bq/kg) in moss from Sokobanja
spa were: 40K 25-427; 226Ra 0.3-36; 232Th 1.0-37; 238U 0.4-28 and 7Be 29-210;
from Banja Jošanica spa they were: 40K 90-242; 226Ra 2.4-11.7; 232Th
2.0-12.7; 238U 1.6-11.3 and 7Be 142-212; Gamzigradska Banja spa: 40K 95-351;
226Ra 8.0-21; 232Th 5.1-19; 238U 6.7-18 and 7Be 20-144. The activity
concentrations of dominant natural radionuclides (potassium, radium, thorium
and uranium) in the moss samples were within the usual ranges for the
territory of Serbia.
