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 number of experiments on the inland transport of sea spray. It is shown that there is a good agreement with data obtained from a wide range of sea spray collection techniques and from both long- and short-term collections. It is concluded that the model is of use in calculating airborne radioactivity concentrations and deposition of radioactivity close to the West Cumbrian coastline. The model can be used to aid estimation of the radiological exposure of persons living in this area from radioactivity discharged into the sea and returned to land by this pathway. (author)
