“…The decrease in 90 Sr is less marked than for 137 Cs in view of the higher persistence of 90 Sr in the aquatic environment. Similarly, the trends of doses from fish intake, arising from the activity concentration of radionuclides in fish, can be explained by the long term accumulation of 90 Sr in fish compared to the fast turnover of 137 Cs in fish flesh (Tracy et al, 2013;IAEA, 2013). The high content of salts in sea water and the consequent low value of the bioaccumulation factor also lead to low levels of 137 Cs concentrations in fish.…”

“…In the framework of the EMRAS II Programme (Tracy et al, 2013), similar contamination scenarios were performed in various regions, aimed at investigating which environments, which components of each environment, and which seasons of the year would be most sensitive to a major release of radionuclides (Carini et al, 2012). The results here obtained are comparable with the analogous estimates from two other models implemented in different coastal marine locations: the NRPA box model applied to various regions in Northern seas (Iosjpe et al, 2002) and the NTUA 3D model applied to the NE Aegean Sea (Psaltaki et al, 2010).…”

“…Approaches to the management of the risk in radioecology have to take into account geographic, climatic, living and dietary habits, as well as ecosystem characteristics (Bäverstam et al, 1997;Hisamatsu et al, 2006). Radiological modelling (Scott, 2003) can provide significant information for the vulnerability of different environments (Håkanson et al, 1996;Tracy et al, 2013) and the environmental sensitivity of a particular ecosystem for radioactive contamination can be an important parameter in environmental management and the policy making (Howard, 2000;IAEA, 2001). In radioecology, the analysis of sensitivity focuses on the evaluation of the impact of the release of radioactive substances on the environment and on the human population.…”

“…Ketergantungan sensitivitas pada faktor-faktor sosial dan ekonomi seperti kebiasaan individu yang hidup, preferensi konsumsi pangan, dan praktek-praktek pertanian. Iklim, geografis, ekosistem, gaya hidup dan perbedaan kebiasaan diet, serta kondisi ekonomi dan sosial, dapat mempengaruhi transfer radionuklida melalui rantai makanan dan dosis untuk populasi manusia [8] . Penentuan konsekuensi dan risiko berdasarkan tipe tapak kota (urban) atau desa akan memudahkan untuk review penentuan tanggap darurat dan mitigasi dampak dari lepasan zat radioaktif (ZRA) di tapak Pembangkit Listrik Tenaga Nuklir (PLTN) [9,10] .…”

ABSTRAKAKTIVITAS DAN KONSEKUENSI DISPERSI RADIOAKTIF UNTUK DAERAH KOTA DAN PEDESAAN. Konsekuensi karena lepasan kontaminan radioaktif oleh manusia dipengaruhi oleh banyak faktor seperti besarnya aktivitas kontaminan yang tersebar dan kondisi lingkungan. Kondisi lingkungan meliputi kondisi meteorologi, kontur tapak, dan pathway kontaminan ke manusia. Tujuan penelitian ini adalah analisis aktivitas dan konsekuensi radionuklida waktu paruh panjang akibat kecelakaan di daerah perkotaan dan pedesaan. Tujuan khusus adalah menghitung aktivitas dispersi udara dan deposisi permukaan, prediksi laju dosis dan risiko yang ditimbulkan untuk daerah perkotaan dan pedesaan sebagai fungsi lokasi. Metode yang digunakan adalah simulasi estimasi konsekuensi dari dispersi produk fisi di atmosfer akibat kecelakaan terpostulasi Beyond Design Basis Accident, BDBA. Perhitungan dilakukan untuk lepasan radioaktif akibat kecelakaan PWR 1000 MWe yang disimulasikan untuk area pedesaan dan perkotaan Tapak Bojanegara-Serang. Hasil analisis aktivitas dispersi udara dan deposisi permukaan untuk area pedesaan (rural) lebih tinggi dibandingkan areal perkotaan (urban). Penerimaan dosis untuk area pedesaan lebih tinggi dibandingkan dengan penerimaaan dosis area perkotaan. Dosis invidu efektif maksimum untuk area pedesaan (rural) adalah 9,24x10-2 Sv dan daerah perkotaan (urban) adalah 5,14x10-2 Sv. Risiko total terkena kanker untuk masyarakat yang berdomisili di area perkotaan lebih tinggi dibandingkan area pedesaan. Kata kunci: aktivitas, konsekuensi, dispersi, perkotaan, pedesaan ABSTRACTTHE ACTIVITIES AND RADIOACTIVE DISPERSION CONSEQUENCES FOR URBAN AND RURAL AREA. The consequences of radioactive releases of contaminants by humans is influenced by many factors such as the amount of activity that spread contaminants and environmental conditions. Environmental conditions include meteorological conditions, the contours of the site and contaminant pathways to humans. The purpose of this research is the analysis of the consequences of radionuclide activity and long half-life time due to accidents in urban and rural areas. The specific objective is to calculate the activity of the air dispersion and surface deposition, dose rate predictions and the risks posed to urban and rural areas as a function of the location. The estimates method used is simulation of the consequences on fission products dispersion in the atmosphere due to the postulated accident Beyond Design Basis Accident, BDBA. The calculation is performed for radioactive releases from accidents in 1000 MWe PWR simulated for rural and urban areas on Bojanegara-Serang site. Results of the analysis are that the activity of air dispersion and deposition surface at rural areas higher than urban areas. The Acceptance dose is higher for rural areas compared with urban areas. The maximum effective individual dose for rural areas is 9.24x10-2 Sv and urban areas is 5.14x10-2 Sv. The total risk of cancer for people who live in urban areas is higher than rural areas.

ABSTRAK PENGARUH KONDISI ATMOSFERIK TERHADAP PERHITUNGAN PROBABILISTIK DAMPAK RADIOLOGI KECELAKAAN PWR 1000-MWe. Perhitungan dampak kecelakaan radiologi terhadap lepasan produk fisi akibat kecelakaan potensial yang mungkin terjadi di Pressurized Water Reactor (PWR) diperlukan secara probabilistik. Mengingat kondisi atmosfer sangat berperan terhadap dispersi radionuklida di lingkungan, dalam penelitian ini akan dianalisis pengaruh kondisi atmosferik terhadap perhitungan probabilistik dari konsekuensi kecelakaan reaktor. Tujuan penelitian adalah melakukan analisis terhadap pengaruh kondisi atmosfer berdasarkan model data input meteorologi terhadap dampak radiologi kecelakaan PWR 1000-MWe yang disimulasikan pada tapak yang mempunyai kondisi meteorologi yang berbeda. Simulasi menggunakan program PC-Cosyma dengan moda perhitungan probabilistik, dengan data input meteorologi yang dieksekusi secara cyclic dan stratified, dan disimulasikan di Tapak Semenanjung Muria dan Pesisir Serang. Data meteorologi diambil setiap jam untuk jangka waktu satu tahun. Hasil perhitungan menunjukkan bahwa frekuensi kumulatif untuk model input yang sama untuk Tapak pesisir Serang lebih tinggi dibandingkan dengan Semenanjung Muria. Untuk tapak yang sama, frekuensi kumulatif model input cyclic lebih tinggi dibandingkan model stratified. Model cyclic memberikan keleluasan dalam menentukan tingkat ketelitian perhitungan dan tidak membutuhkan data acuan dibandingkan dengan model stratified. Penggunaan model cyclic dan stratified melibatkan jumlah data yang besar dan pengulangan perhitungan akan meningkatkan ketelitian nilai-nilai statistika perhitungan. Kata kunci: dampak kecelakaan, PWR 1000-MWe, probabilistik, atmosferik, PC-Cosyma ABSTRACT THE INFLUENCE OF ATMOSPHERIC CONDITIONS TO PROBABILISTIC CALCULATION OF IMPACT OF RADIOLOGY ACCIDENT ON PWR-1000MWe. The calculation of the radiological impact of the fission products releases due to potential accidents that may occur in the PWR (Pressurized Water Reactor) is required in a probabilistic. The atmospheric conditions greatly contribute to the dispersion of radionuclides in the environment, so that in this study will be analyzed the influence of atmospheric conditions on probabilistic calculation of the reactor accidents consequences. The objective of this study is to conduct an analysis of the influence of atmospheric conditions based on meteorological input data models on the radiological consequences of PWR-1000MWe accidents. Simulations using PC-Cosyma code with probabilistic calculations mode, the meteorological data input executed cyclic and stratified, the meteorological input data are executed in the cyclic and stratified, and simulated in Muria Peninsula and Serang Coastal. Meteorological data were taken every hour for the duration of the year. The result showed that the cumulative frequency for the same input models for Serang coastal is higher than the Muria Peninsula. For the same site, cumulative frequency on cyclic input models is higher than stratified models. The cyclic models provide flexibility in determining the level of accuracy of calculations and do not require reference data compared to stratified models. The use of cyclic and stratified models involving large amounts of data and calculation repetition will improve the accuracy of statistical calculation values. Keywords: accident impact, PWR 1000 MWe, probabilistic, atmospheric, PC-Cosyma
