Almost ten years after the Chernobyl accident, the March 1996 IAEA Bulletin edition focuses on the impacts and influences it has had and continues to have in various fields. Nuclear power's development has slowed over the past 10 years. The IAEA's co-operative programme is consolidating the technical basis for further upgrading the safety of Chernobyl-type reactors. Scientists at the IAEA's Marine Environment Laboratory in Monaco have played an integral role in post-Chernobyl studies. Criteria have been established at the international level to guide decisions about protective actions after a nuclear or radiological emergency. New information presented at an IAEA symposium is helping the global community address radioecological concerns. The IAEA, UNESCO, and Italy strengthen their co-operative support of the International Centre for Theoretical Physics. This edition also includes an issue of Inside Technical Co-operation, which covers several of the current IAEA?s Technical Cooperation projects.
