Sažetak
A spatial radionuclide distribution in recent estuarine sediments in the Krka River Estuary was studied. Human activities affected a natural geochemical equilibrium of radionuclides in the area studied. The sediment samples have been analysed during the past two years and the activities of 40K, 232Th, 226Ra, 238U and 137Cs were determined by a gamma-spectrometry method. The radionuclide distribution data indicate a different sedimentation rates of the marine and/or terrigenous origin. A difference in the transport rates of the dissolved and suspended material is clearly indicated by the 137Cs and 40K contents in the sediments at the upper estuary.
