Monitoring of environmental radiation due to the presence and operation of nuclear facilities in a certain area is an absolute requirement that must be fulfilled according to Government Regulation No. 2/2014 for reactor and non-reactor facilities and No. 29/2008 for the use of ionizing radiation. This evaluation was carried out to support the effectiveness of the Environmental Radiation Monitoring at Serpong Nuclear Facility Area (SNFA) as well as part of the national research program on radiation monitoring systems for safety and security development. As the model, Serpong Nuclear Facility Area contains six nuclear facilities that contribute to SNFA Environment Radiation. Each facility assumed contributes to the radiation measurement following Gaussian Atmospheric Dispersion Model. By evaluating source terms from six nuclear facilities, formula of Gaussian Dispersion, and meteorology data, we can estimate the model ambient concentration and doses as 0.04-0.025 (μSv/h). This model result, then, was compared with installed radiation monitoring data as well as mobile measuring data, and the result shows the consistency of the radiation dose of measurement of 0.01 – 0.07 µSv/h when the Cs-137 was assumed neglected. The t-test of the operation and shutdown measurement data showed no significant difference of data measurement during the shutdown and operation phase of the reactor. It means that the impact of radiation release during normal operation and shutdown is not significant. In general, the result shows that the simple atmospheric dispersion model is suitable model to estimate ambient concentration and ambient dose at the location where the radiation monitoring station is installed.
