!Analytical evaluation of pollutioninduced radiation level effects on humans at sea
Planning and implementing various projects concerning possible radioactive pollution of sea requires predicting radiation impact on people. Radiation pollution of water areas with operating and repaired floating A-plants, nuclear ships and vessels, stored fragments of nuclear submarines designed for recycling and decommissioned submarines as well as radiation pollution of the open sea influence people in different ways. The main way of the radiation impact if the open sea is polluted is that people consume sea food coming from the polluted areas. On the contrary, radiation pollution of the water areas with military and industrial nuclear objects has direct effect on humans, even if these water areas are at considerable distances. In the latter case the main way of radiation impact is external radiation coming from water and inhaling radionuclides. To perform quantitative assessment the authors have analytically modeled each of the above mentioned radiation ways and recommended the assessment method for the radiation impact concerning radi ation impact of the sea. The peculiarity of this method is that it uses dose coefficient transforming volumetric activity of the sea water in the polluted area into efficient radiation dose for population including fishing as well as various industrial activities at the places where nuclear facilities are located and repaired. The paper gives calculated dose coefficients and formulas to define efficient radiation dose for each of the above mentioned sea areas subjected to radiation pollution
