วิเคราะห์นิวไคลด์กัมมันตรังสี (226Ra, 232Th, 40K) ของพืชจาก ตำบลตาชี อำเภอยะหา จังหวัดยะลา

Abstract

Radionuclides were obtained from sources such as natural processes and human activities. The objective of this research activity is to evaluate the phytoremediation potential of various plants grown in soils contaminated with radionuclides in Tache Sub District, Yaha District, Yala Province. This area is a mountainous plateau and was once a mining site. So it is filled with radioactive materials. The most densely populated plants in this are. 16 types. Examine the potential for the transfer factor radionuclide from soil to plants. is Climbing Wattle, Cassava, Phraao Nok Khum, Thorn Apple, Spanish needle and Bitter bush. The potential to transfer factor of radionuclide was well (TF>1). Therefore bring all 6 plants to study thoroughly by separating each plant into root, stem, and leaves. Experiment by dividing into the cement pond and planted in plots. The duration of the experiment is 6 months. Collected is a date every 3 months. Both experiments were radionuclide of 226Ra, 137 Cs, 28U, and 22Th all of the plants less than 1 (TF<1). Except for the amount of transfer factor radionuclide of 40K all of the plants is greater than 1 (TF> 1). and most commonly in the roots of Phraao Nok Khum was 7,45÷0.45 and 9.13+0.33 respectively. The beginning of the shoot of Phraao Nok Khum was 5.38+0.31 and 5.49÷0.20 respectively. This study showed that Phraao Nok Khum has the potential to transfer factor can be an option for the treatment of radionuclides in soil in the other areas.
