AN EXPERIMENTAL STUDY OF THE RADIOACTIVITY ASSOCIATED WITH SOIL AND DUST PARTICLES IN THE VICINITY OF THE CHERNOBYL NUCLEAR POWER PLANT

Abstract Within the 30 km exclusion zone around the Chernobyl nuclear power plant, soil composition, the distribution of activity in different soil fractions and resuspended dust particles resulting from technogenic (i.e. mechanical) activity have been investigated. In addition, experiments have been carried out on the size distribution of fuel particles within soils. Some work was also undertaken to enable the estimation of resuspension factors and deposition velocities of particulate materials in this area.
