Title: The use of Eupatorium Odoratum as bio-monitor for radionuclides determination in Manjung, Perak

The accumulation of radionuclides in plants can be used as bio-monitoring in the environment. This technique is a cost-effective as the plants used to uptake deposited radionuclides from soil, commonly as soil-to-plant transfer factor (TF), which is widely used for calculating radiological risk. Radionuclides deposited in the soil carry by the air as particles or gases lead to the accumulation in soil. Eupatorium odoratum, known as pokok kapal terbang in Malaysia was chosen as sample for their abundances and properties to measure surface soil contamination. The plants were collected in three different directions (North, North-East and South-East) from Manjung district. The plants were collected in same size and then separated in to three parts (roots, stems and leaves) to determine the transfer factor from soil to each part. The concentrations of thorium (Th) and uranium (U) were analyzed using Energy Disperse X-Ray Fluorescence (EDXRF) and found in the range of 1.20-3.50 mg/kg and 1.20-3.90 mg/kg in roots, 1.40-3.90 mg/kg and 1.50-5.90 mg/kg in stems and 1.50-2.50 mg/kg and 2.00-6.00 mg/kg in leaves, respectively. Transfer factor (TF) was calculated through concentrations as reported in this article and show that the plants have transferred and accumulated radionuclides in significant values. From radionuclides concentrations in topsoil, the radiological riskmore » was calculated and the present result show that external hazard index (H{sub ex}) is below than unity indicate low radiological risk at that area.« less
