A MODEL OF THE TRANSFER OF RADIOACTIVITY FROM SEA TO LAND IN SEA SPRAY

A model of the transfer of radioactivity from sea to land in sea spray is described. The model involves a simple analysis of the atmospheric dispersion and deposition of sea spray droplets produced in the surf zone. Results obtained using the model are compared to data from a num ber of experiments on the inland transport of sea spray. It is shown t hat there is a good agreement with data obtained from a wide range of sea spray collection techniques and from both long- and short-term col lections. It is concluded that the model is of use in calculating airb orne radioactivity concentrations and deposition of radioactivity clos e to the West Cumbrian coastline. The model can be used to aid estimat ion of the radiological exposure of persons living in this area from r adioactivity discharged into the sea and returned to land by this path way.
