This publication is the CD-ROM proceedings of the 2003 International Conference on `Isotopic and Nuclear Analytical Techniques for Health and Environment' organized by the IAEA. The conference brought together scientists, technologists and representatives of industry and regulatory authorities to exchange information and review the status of current applications of isotopic techniques and nuclear analytical techniques (NATs). Future trends and developments of NATs were also discussed. Potential opportunities were identified for application of isotopic techniques and NATs in health and environmental studies in developing countries, and mechanisms were explored for promoting and transferring such technologies. The purpose of the conference was to address developments and trends in health care, nutrition and environmental monitoring, and to exchange information in an international forum to identify future fields of application for isotopic techniques and NATs. In a round-table discussion, the conference addressed possible means and mechanisms for knowledge management and knowledge preservation in areas where interest in nuclear energy and nuclear applications is discouraged and declining, and for building capacity in areas where development potential is still available.
