This publication presents the proceedings of an international conference on remediation of radioactive contaminated sites with a particular focus on the states of Central Asia. The conference provided a forum for all parties involved in remediation of such sites to gather and exchange ideas, review progress and new developments, compare technologies and methods, and thus disseminate information and experience. The key topical issues identified and discussed by the participants included regulatory and safety regimes, innovative and mature technologies, life cycle planning, technical experience exchange, stakeholder issues, and international cooperation and support. A series of case studies are presented to provide an overview of environmental remediation activities in different parts of the world. The publication summarizes the present status, and outlines future trends in environmental remediation technologies and methods, and identifies possible areas for improvement.
