- Abstract
This Particulate nuclide deposit onto the sea surface will bring radioactive hazards to marine ecological environment, so it is necessary to study the dry deposition velocity of it onto sea surface. In this paper, a model of dry deposition of particulate nuclide onto sea surface is established, and the reliability of the model is verified by experimental data. Then, effects of the diameter, wind speed, and particle density on dry deposition velocity is analyzed. It is found that (1) For small nuclides, the deposition velocity is inversely proportional to diameter; for large nuclide, that is proportional to the diameter. (2) For very small diameter nuclides, the larger wind speed is, the higher dry deposition velocity is. for larger particles, that is insensitive to wind speed; (3) The influence of nuclide particle density on dry deposition velocity is related to the diameter. The dry deposition velocity of nuclide particle with a small diameter is insensitive to the density, and that of large diameter particle is proportional to the density. The results of this paper will help to accurately predict the spatial and temporal distribution of nuclide in ocean atmospheric and the amount of nuclide deposited on the sea surface.
