“…Cs activity concentration was not caused by salinity, but it was most likely caused by the station's proximity to the estuary and its being the nearest station to the industrial waste effluent of Gresik that contained ions capable of scavenging 137 Cs. Zalewska and Lipska [24] found that reduction of the activity concentration of 137 Cs occurs at stations closest to river-estuaries and in low-salinity water, because there 137 Cs is diluted by freshwater, and because the behavior of the radionuclide in the water column is affected by physical processes such as advection, mixing, and diffusion [25,26].…”

“…Furthermore, the ERICA Integrated Approach recommends the use of expected values (or best estimates) of activity concentrations. The assessment chronology in this study uses normal 137 Cs activity concentration in seawater and sediment [20]. On other hand, the distribution coefficient (K d ), CF, radiation weighting factor, and uncertainty factor in each organism were taken from secondary data which is prepared by ERICA.…”

The present trend of global warming has led to an increase in seawater temperature and salinity. The effects of increasing salinity and temperature on the accumulation of 137 Cs by milkfish Chanos chanos was studied under laboratory conditions to obtain information on Chanos chanos adaptability under environmental changes. The uptake of radioactive cesium by Chanos chanos increased with temperature of seawater. The concentration factors (CF) of 137 Cs for temperatures of 25°C, 27°C, 29°C, and 31°C at steady state period were 5.25, 5.91, 6.78, and 9.98 mL g -1 for the whole-body of Chanos chanos. The concentration factors at steady state (CF ss ) of 137 Cs for salinities of 26‰, 29‰, 32‰, and 35‰ were 6.23, 9.93, 9.24, and 6.86 mL g -1 , respectively. After temperature exposure to 31°C, the fish gills showed hyperplasia of epithelial cells in branchial secondary lamellae, congestion of blood vessels, and hypertrophy of pillar cells. The fish from the treatment group exhibited hemorrhage between the branchial secondary lamellae and an abundance of mucous substance in comparison with control group. This study links radionuclide bioaccumulation data and monitoring data obtained in the field and laboratory experiment with radiation dose determined by ERICA Tools, an approach that will enable better linkages to be made between exposure and dose in Chanos chanos and its marine food web.

“…According to a study conducted by K. Hirose, radionuclides originated from the acciddent spreads mainly in the north part of the Northern Hemisphere atmosphere [1]. This was also confirmed by studies on marine biota in Malaysia [2] based on ERICA tool [3] and Indonesian ocean [4,5]. However, public concern on the safety of a nuclear facility rises all over the world and, hence, the related authority needs to response to this public concern.…”

DESIGN, IMPLEMENTATION AND VERIFICATION OF SOFTWARE CODE FOR RADIATION DOSE ASSESSMENT BASED ON SIMPLE GENERIC ENVIRONMENTAL MODEL.Radiation dose assessment to determine the potential of radiological impacts of various installations within nuclear facility complex is necessary to ensure evironmental and public safety. A simple generic model-based method for calculating radiation doses caused by the release of radioactive substances into the environment has been published by the International Atomic Energy Agency (IAEA) as the Safety Report Series . In order to assist the application of the assessment method and a basis for the development of more complex assessment methods, an open-source based software code has been designed and implemented. The software comes with maps and is very easy to be used because assessment scenarios can be done through diagrams. Software verification was performed by comparing its result to SRS-19 and CROM software calculation results. Dose estimated by SRS-19 are higher compared to the result of developed software. However, these are still acceptable since dose estimation in SRS-19 is based on conservative approach. On the other hand, compared to CROM software, the same results for three scenarios and a non-significant difference of 2.25% in another scenario were obtained. These results indicate the correctness of our implementation and implies that the developed software is ready for use in real scenario. In the future, the addition of various features and development of new model need to be done to improve the capability of software that has been developed.Keywords: Radiation dose assessment, software code, radioactive discharge, environment, IAEA SRS-19. ABSTRAK PERANCANGAN, IMPLEMENTASI DAN VERIFIKASI PERANGKAT LUNAK UNTUK KAJIAN DOSIS RADIASI BERBASIS MODEL LINGKUNGAN GENERIK SEDERHANA. Kajian dosis radiasi untuk mengetahui potensi dampak radiologi akibat pengoperasian berbagai instalasi yang ada di dalam kawasan instalasi nuklir sangat diperlukan untuk menjamin keselamatan masyarakat dan lingkungan. Metode sederhana berbasis model lingkungan generik untuk menghitung dosis radiasi yang disebabkan oleh pelepasan zat radioaktif ke lingkungan telah diterbitkan oleh International Atomic Energy Agency (IAEA) sebagai Safety Report Series
