Proceedings of a symposium jointly organized by the IAEA and FAO, Vienna, 18–22 June 1990. The technology of mutation induction has been accepted by plant breeders as a valuable additional tool for creating improved cultivars for agriculture and horticulture. It was amply demonstrated at the symposium that this technique has been applied with great success in many annual seed propagated crops such as rice, barley, wheat, cotton, soybean and pea. The technological problems identified primarily concerned vegetatively propagated crops and, in general, the logistic difficulties in identifying desirable mutants in large mutagenized populations.
Contents: (Vol. 2) Mutation breeding with particular objectives; Methodology of mutation breeding; Panel: Part 1: The role of plant breeding for the future of mankind and the need for genetic resources and opportunities for mutagenesis or gene engineering; Part 2: Plant mutation breeding: Its future role, the methodology needed, training and the research priorities.

Proceedings of a symposium, Vienna, 5–8 June 1990. Over the past decades, many nuclear techniques have been developed and used on an industrial scale for the exploration and exploitation of energy and mineral resources, resulting in very great technical and economic benefits. The major nuclear techniques which are currently employed on a large scale include nucleonics control and on-stream analysis, nuclear well logging and tracer investigations. The advantages of nuclear techniques include rapidity, relative simplicity and, in some cases, the possibility of use in hostile environments where no other methods can be used. Furthermore, nuclear measurements and nucleonics control can be made by non-contact processes. The purpose of the symposium was to review the latest concepts and developments and to foster an exchange of information leading to technology transfer from developed to developing countries.
Contents: Nucleonics control systems and on-stream analysers in the coal industry; On-line nuclear and nuclear related analytical techniques in the mineral industry; Nucleonics control systems and on-stream mineral analysers; Nuclear borehole logging applications; Nuclear borehole logging instrumentation, data processing and interpretation; Tracer techniques and radiometric methods in the mineral industry; Off-line nuclear activation analysis in the mineral industry; Summary of the panel discussion: Nuclear and nuclear related techniques in the mineral industry — trends and future perspectives.

Proceedings of a symposium, Munich, 7–11 May 1990. The expanding application of ionizing radiation in medicine, industry and research calls for vigorous promotion of effective radiation protection efforts, not only to prevent any unsafe practices but also to assess correctly and provide authoritative information on the safety of adopted practices. The purpose of the symposium was to review experience gained in Member States with existing infrastructures for ensuring radiation safety and to discuss how safety standards could most effectively be applied in the national context.
Contents: Regulation and licensing; National infrastructures; Education and training; Personnel dosimetry services; Control programmes; Services and special issues; International activities; Panel: The role of the IAEA in strengthening radiation protection infrastructures.

Proceedings of a symposium jointly organized with FAO, UNEP and WHO, Vienna, 16–20 October 1989. Scientific research on the after-effects of the Chernobyl accident on the environment and on human health has provided new data pertaining to large scale contamination. Papers at the symposium covered a wide range of subjects, including monitoring of radioactive contaminants in the environment, levels of radioactive contamination of farmland, agricultural crops and dairy products in subsequent years, and methods for minimizing contamination of feed and food.
Contents: Vol. 1: Part I: Radioactive contamination of the envi-ronment: (a) General; (b) Air; (c) Soil; (d) Water; Part II: Monitoring of radioactivity: (a) General; (b) Strategies and policy; (c) Methods and techniques. Vol. 2: Part III: Radioactive contamination of agricultural land and agricultural produce; Part IV: Countermeasures to reduce radionuclide contamination of food chains; Part V: Radiation exposure of populations; Part VI: Radionuclides and international trade in food; Special Session: Hot particles; Summary of the symposium: Important issues with significance for the future.

Proceedings of a symposium, Vienna, 6–10 November 1989. The purpose was to provide a forum for review of actual experience gained and lessons learned from recovery techniques and operations in response to serious accidents at nuclear facilities and accidents associated with radioactive materials, and also to consider the development of emergency planning and preparedness resources. A special feature of the symposium programme was a full session on an accident involving a chemical explosion in a high level waste tank at a plutonium extraction plant in the Southern Urals in the USSR in 1957.
Contents: Recovery operations from accidents with radioactive materials; On-site recovery operations (nuclear facilities); Offsite recovery operations (nuclear facilities); The accident in the Southern Urals in 1957; Lessons learned from radiological accidents.

Proceedings of a symposium, Vienna, 27 February to 3 March 1989. Within the last decade there has been considerable development in fire protection and nuclear designers now recognize its importance at all design stages. While the principles of fire protection have been implemented worldwide, problems are still apparent in the description of specific aspects of fire behaviour, material properties, system performance, etc. The symposium provided a forum for the discussion of these and other questions.
Contents: Standards and licensing; National fire safety practices; Fire safety by design; Fire fighting and a panel on: How to manage real fires once they occur; Computer fire modelling; Fire safety in fuel cycle facilities; Fire testing of materials; Fire risk assessment; Closing statement.

Proceedings of a symposium, jointly organized by the Federal Republic of Germany, IAEA and OECD/NEA, Munich, 7–10 November 1988. The overall emphasis was placed on the international aspects of nuclear safety.
Contents: Opening session; National regulatory practices and safety standards; National regulatory systems; Implementation of regulatory practices (technical issues); Implementation of regulatory practices (operational aspects); Development and trends in safety standards and practices; International aspects; Implementation of developments in safety standards and practices (Panel I); International harmonization of safety standards and practices — Need, possibilities and limitations (Panel II).
