Heavy metals in soils, water, and cassava plants around Pacitan Coal-fired Power Plant were analyzed using k0-NAA method so that their distribution pattern could be determined. The k0-NAA method was validated first by determining z-score. The results of analysis were used to determine Biocentration Factor (BCF). The soil sample was ground and sieved. The cassava leaves and cassava roots were freeze dried with liquid N2, ground, and sieved. The water sample preparation was performed by evaporating it until the volume was 1/40 from the original. Au-Zr foil was used as flux monitor. The samples were irradiated together with flux monitors, secondary standards, SRMs, and blanks. Samples interpretation was performed with support of Genie 2000, Hypermet 5.12, and k0-IAEA software. The k0-NAA method was considered valid based on the analysis results of SRM where |
