Purpose of this study was to measure activity concentration
for radionuclides Th-232, K-40, and total uranium (U-Sigma) using HPGe detector in samples
collected from the three levels of bank profiles (A-alluvial soil level, OB-overbank level, S-
active stream level) in the West Morava River basin, Serbia. External dose equivalent was
estimated as well as inhalation and ingestion lifetime cancer morbidity risks. External dose
equivalent was obtained using Monte Carlo package FOTELP. Mean activity concentrations are (393
Bq/kg - A, 378 Bq/kg - OB, 346 Bq/kg - S) for K-40, (29 Bq/kg - A, 24 Bq/kg - OB, 23 Bq/kg - S)
for U-Sigma and (31 Bq/kg - A, 30 Bq/kg - OB, 22.5 Bq/kg - S) for Th-232. Mean value of
calculated cancer morbidity risk from Th-232 inhalation is 0.94x10(-6), range (0.35 - 1.4) x10(-
6) and for ingestion 1.7x10(-6), range (0.6 - 2.5) x10(-6). Mean value of calculated cancer
morbidity risk from U-238 inhalation is 0.2x10(-6), range (0.07-0.3) x10(-6) and from ingestion
0.43 x10(-6), range (0.17-0.58) x10(-6).
