Long-Term Contamination of the Arabian Gulf as a Result of Hypothetical Nuclear Power Plant Accidents

Long-term consequences of radionuclide contamination the Arabian Gulf as a result hypothetical accidents at Bushehr and Barakah nuclear power plants (NPPs) were studied using chain models including atmospheric dispersion model RIMPUFF, marine compartment POSEIDON-R, dose model. The POSEIDON-R is complemented by dynamic biota food that includes both pelagic benthic organisms. source terms for releases selected radionuclides (134Cs, 137Cs, 106Ru, 90Sr) in atmosphere defined fraction respective reactor inventories available literature. Conservative meteorological scenarios calculation initial depositions selected. Because shallow, significant portion reactive 106Ru) remain bottom sediments continue to contaminate water organisms long period time. annual due consumption products can exceed 1 mSv, whereas drinking from desalination expected be an order less. contribution elements depends on type reactor. This manifested differences between contributions different dose.
