The secure management of nuclear and radioactive wastes is a topic that has currently received huge recognition due to the large amount of accumulative wastes and the increased public awareness of the hazards of such wastes. This book caters to the practice and research efforts that are lately conducted to deal with the technical problems in various radioactive waste management acts and to introduce the non-technical factors that can affect the management applications. The book includes an introductory section and a section under pre-disposal activities of radioactive waste management. The authors have covered the management system; presented how old management methods and radioactive accident can affect the environment and summarized the information gained from latest management applications and results of research efforts for using some innovative techniques in both pre-disposal and disposal acts.
