摘 要:The main aim of this study is to determine the activity concentrations of uranium series and thorium series radionuclide in crops cultivated in Upper *** types of cereal crops were collected from local markets and analyzed by γ-ray *** mean activity concentrations of the natural radionuclides 238U,226Ra and 232Th were 0.67,1.27 and 0.56 Bq·kg-1,*** annual effective doses from these radionuclides were estimated for different age groups.
