Determination of 239,240Pu and 241Am in the Cisadane river sediment and surface soil samples collected in 1996 from the environment of Atomic Energy Research Establishment (PPTA) of Serpong has been carried out. The objective of research was to evaluate the existence of 239,240Pu and 241Am in the environment as impact of nuclear activities in the PPTA Serpong. Surface soils were collected from 3 locations and each of location consists of 4 sampling sites. Cisadane river sediment consists of 3 sampling sites. The results showed that the average concentration were founded to be 17.03 ± 2.49 mBq/kg for 239,240Pu and 9.20 ± 2.93 mBq/kg for 241Am. The observed 239,240Pu and 241Am concentration are low compared to the reported values for some other areas of the world. The Activity ratios of 241Am/239,240Pu and 239,240Pu /137Cs in surface soils were found to be in the narrow range 0.32 to 0.53 with a mean value of 0.43 ± 0.09 and 0.017 to 0.029 with a mean value of 0.024 ± 0.005 respectively. This ratio is in excellent agreement with the value of global fall-out.
