Transfer Factor of Radionuclides from Soil to Plant

In the present study an environmental radiation and determination of contamination of natural radionuclides such as Uranium, Thorium and Potassium in soil and herbs (Salsola imbricate) detected in The total of 20 samples (10 soil samples and 10 plant samples) were collected at 20th July, 2016 from different sites in Nahrawan hand is one of the aspects of Iraq to eliminate the towns in the province of Baghdad, in the west of the capital, And the northern part of which is located near the meeting place of the Diyala River with the Tigris River, and is an agricultural area originally recently turned into a city in the suburbs and the site actually contaminated with military equipment through 2003. The transfer factor (TF) of uranium for five different sites was measured by the Gamma ray spectroscopy and high-purity Germanium (HPGe) detector the transfer factor for 238U ranged 0.00019, 0.24. Whereas the TF values of thorium were found to be ranged 0.09 to 1.24. On the other hand for potassium the TFs values ranged from (0.9 to 5.1). The transfer factor values in the present study are satisfied the standards of IAEA except TF for 40K in plant species were found to be higher than IAEA value. The data compiled by IAEA for soil to plant transfer factor of 40K in leaves was in the range of (0.49 to 5.6) with average value of (1.4).
