Modelling and assessment of the impact of radiocesium and radiostrontium contamination in the Thermaikos Gulf, Greece

Assessment of marine radiological impact after an hypothetical nuclear accident in Eastern Mediterranean Sea

“…In order to simulate the radionuclides dispersion in the marine environment, the additional processes of nuclear decay and particles' phase transfer have also been included into the model [7], following a stochastic approach where at each computational time step Δt a random number r between 0 and 1 is generated for each particle and it is compared with the probability p given by the equation:…”

“…In this frame, several projects aiming to improve the capabilities of simulation radiomodels and decision support systems have been released by the International Atomic Energy Agency (IAEA) [2][3][4][5]. For the Mediterranean Sea, radiological models have been developed in regional and local scales focusing on the fate of 137 Cs after the Chernobyl accident [6][7][8][9]. Eastern Mediterranean Sea is of particular interest, since it is rapidly affected by climate change and extensive anthropogenic pressures, including radiological threat.…”
