The main source of 137 Cs radioactive releases categorized as global fallout came from nuclear weapon experiments in the past as well as nuclear accidents of the Chernobyl and Fukushima nuclear power plant that occurred in 1986 and 2011. Radioactive contamination in the atmosphere will be deposited on land and dispersed through the water. The existing operational nuclear facilities and government plan to construct an Experimental Power Reactor in the Serpong Puspitek area could potentially release radioactive 137 Cs through the Cisadane river towards into Jakarta Bay. Environmental monitoring of fission products is required to control the level of radioactivity of the marine environment when the new nuclear facilities and existing facilities operate. On the other hand, the old unit has a weakness of adsorption efficiency and suspected not perfectly coated in filter cartridges. Compared with the old design, this unit easily mobilized and integrated with the measurement of seawater parameters refers to pH, conductivity, and temperature. This unit fulfilled IAEA analytical guidelines with the results of decision threshold and detection limit were 0,13 mBq/l and 0,29 mBq/l respectively, also the results of the relative bias and precision test are below the permissible limit.
