Study Of Transfer Factors For Radionuclide And Heavy Metal In Bananas (Musa Paradisiaca) At Tarahan-Lampung As Supporting Data For National Food Security National Research And Innovation Agency - BRIN Abstract The Tarahan-Lampung Coal Steam Power Plant (CFPPs) is one of the largest CFPPs on the island of Sumatra. CFPPs may produce hazardous trace elements (HTEs) and contribute to air pollution. Since bananas are a major commodity in Lampung, it^s crucial to assess the presence of radionuclides and heavy metals in bananas intended for consumption. To accomplish this, a study was conducted to analyze the activity of radionuclides (226Ra, 228Th, 40K, 137Cs) and the heavy metal content (Fe, As, Pb, Hg, Zn) in soil and banana samples from the industrial area around CFPPs-Tarahan. The analysis involved using a High Purity Germanium Detector (HPGe) gamma spectrometer to determine radionuclide activity concentration and X-Ray Fluorescence (XRF) to measure heavy metal concentrations. The highest activity concentration for 226Ra, 228Th, 40K, and 137Cs in soil were 54, 64, 714, and 0.4 Bq/kg, respectively. The concentrations of heavy metals Fe, As, Pb, Hg, and Zn were also determined, producing the following values: 39100, 14, 27, 3, and 221 μ-g/g. For bananas, the highest activity values of 226Ra and 40K were 15 and 414 Bq/kg, respectively, with no activity of 228Th and 137Cs found. The highest concentrations of heavy metals Fe, Pb, and Zn in dried and wet banana samples were 68, 1.9, 11, and 46.9, 1.4, 7.3 μ-g/g, respectively. The average value of the radionuclide transfer factor from soil to plants for each radionuclide 226Ra and 40K was 0.3 and 1.2, respectively, while transfer factor values for 228Th and 137Cs were not detected.
