US port throughput of radioactive materials: a twenty-year study

This study documents that more than a half million tons of radioactive and associated materials, including wastes, were handled at US ports between 1965 and 1984. Although some ports were dominant, radioactive traffic flowed through a large number of ports. An analysis of concordance demonstrates agreement in port rankings over the 20-year period. Large, medium and small ports are identified via a cluster analysis.
