Transfer factors of 40K, 226Ra, 232Th from soil to different types of local vegetables, radiation hazard indices and their annual doses

This work aims to determine the transfer factors (TFs) of 40 K, 226 Ra and 232 Th from soil to vegetables, because there are few surveys of them in Iraq. The samples were taken from three important agricultural areas supplying the vegetable products needed by the Iraqi population. Using NaI(Tl) tech...

Description
Summary:This work aims to determine the transfer factors (TFs) of 40 K, 226 Ra and 232 Th from soil to vegetables, because there are few surveys of them in Iraq. The samples were taken from three important agricultural areas supplying the vegetable products needed by the Iraqi population. Using NaI(Tl) technique, the average values of TFs of the above radioactive isotopes were found to be 0.60, 0.41, 0.59 and 0.05, 0.03, 0.05 from soil to dry and fresh samples, respectively. The radiation hazard indices and the total annual dose were found to be within the range of the world values.
