Proceedings of an international conference jointly organized by the EC, IAEA, Interpol and WCO and held in Dijon, France, 14-18 September 1998. The conference was the first of its kind devoted to this subject and brought together radiation safety experts, regulators, and customs and police officers, in order to foster information exchange through a review of the state of the art and open discussions. The need was expressed for the formulation of international recommendations concerned with the effective operation of national systems for ensuring the safety of radiation sources and the security of radioactive materials. These proceedings contain the keynote address, the invited papers, summaries of discussions and session summaries. Together with IAEA-TECDOC-1045, published in 1998 prior to the conference, they constitute the complete record of the conference.

Proceedings of an international conference, jointly sponsored by the European Commission, IAEA and WHO, and held in co-operation with UNDHA, UNESCO, UNEP, UNSCEAR, FAO and OECD/NEA, Vienna, 8-12 April 1996. Two major objectives were to reach agreement on established scientific facts and to clarify their interpretation in order to promote comprehension of the consequences of the Chernobyl accident and to help dispel misapprehensions. Background papers were prepared by teams of scientists from around the world who collaborated to ascertain and present the current state of knowledge on the health and environmental consequences of the accident. Nuclear safety aspects and the accident's social and economic impact were also considered, as well as the conclusions drawn at related conferences and in other national and international projects. The conference was attended by more than 800 experts in the field of radiation protection and nuclear safety, including medical, environmental and engineering specialists. The conference did much to achieve a broad consensus on the accident's consequences and to consolidate a common understanding of their nature and magnitude. In particular, the results of the conference will assist those countries most affected by the consequences in developing well informed and balanced policies for their alleviation. The proceedings contain a summary of the conference results and the texts of oral presentations and discussions, while an IAEA technical document (TECDOC) will reproduce material from 181 poster presentations as well as the List of Participants.

Proceedings of a symposium, Vienna, 24–27 May 1993. Accurate dosimetry is of great importance for applications of radiation in medicine. The symposium covered all the various steps required in the calibration chain to determine the absorbed dose in radiotherapy. Different calibration procedures at primary and secondary standard laboratories were discussed, and reports were presented on dose intercomparisons based on different national and international protocols. Analyses of the accuracy of various interaction coefficients were also presented. The final session dealt with the special problems of diagnostic X ray dosimetry.
Contents: Status of primary standards for absorbed dose, exposure and kerma; Intercomparison, dissemination and transfer; Calibrations and quality assurance programmes; Dose, volume and quality specifications; Interaction coefficients and correction factors; Application of different protocols for absorbed dose determination; Plane parallel chambers; Beam quality dependence; Direct calibration in absorbed dose to water; Diagnostic X ray dosimetry.

Proceedings of a symposium, Vienna, 19–23 April 1993. Natural isotopes are among the most powerful tools for investigating past and current environmental changes. In particular, stable isotopes have proved to be very useful proxy indicators of climate related parameters such as surface air temperature, relative humidity of the atmosphere and amount of precipitation, whereas radioactive isotopes are widely used as a dating tool. The release of radionuclides during nuclear bomb tests permitted studies of the dynamics of transport and mixing processes in the atmosphere. It also allowed a global tracer experiment on the hydrological and carbon cycles, which substantially contributed to better understanding of these two vital compartments of the global ecosystem. A wide spectrum of themes was discussed at the symposium, covering both the ‘present’ and the ‘past’ of the global atmosphere/hydrosphere system. Case studies as well as methodological aspects of various isotope techniques applied in both areas of research were presented.
Contents: Isotopes in atmospheric studies; Isotopes in the soil–plants–atmosphere system; Degradation of water resources; Palaeohydrology and palaeowaters; Isotope indicators of climatic changes; Poster presentations.

Proceedings of a symposium jointly organized by the IAEA, FAO and WHO, Aix-en-Provence, 1–5 March 1993. Natural isotopes are among the most powerful tools for investigating past and current environmental changes. The purpose of the symposium was to evaluate the costs and benefits of irradiation for treating various food items either alone or in combination with other processes. The evaluation covered applications of the technology in terms of reducing food losses as well as the possible economic impact of irradiation in controlling or reducing certain food-borne illnesses and in expanding trade in certain food items. Discussion focused on the economic benefits of irradiation to control a number of food-borne diseases, especially those originating from the consumption of food of animal origin, and on the potential economic benefit from radiation as a quarantine treatment for fresh fruits and vegetables.
Contents: Keynote address; Food safety; Food losses; Irradiation facilities; Food trade; Technology transfer; Commercial and new applications.

Proceedings of a symposium jointly organized by the IAEA and FAO, Vienna, 19–23 October 1992. In the past decade significant progress has been made in overcoming many of the difficulties of biologically based methods of pest management. Particularly important are the advances made in the field of molecular technology and biotechnology. Presentations in this symposium focus on advances and trends in insect control and eradication, genetic engineering and molecular biology, insect genetics, operational SIT programmes, F1 sterility and behaviour, biocontrol, tsetse fly R&D, and quarantine.
Contents: Genetic engineering and molecular biology; Genetics; Operational programmes; F1 sterility and insect behaviour; Biocontrol; Research and development on the tsetse fly; Quarantine.

Proceedings of a symposium organized jointly with CEC and OECD/NEA, Antwerp, Belgium, 19–23 October 1992. The purpose of the symposium was to review the progress being made in national and international programmes towards the demonstration of safe disposal of radioactive wastes. The technical presentations addressed disposal in all the principal geological media currently under consideration: clay, crystalline rock, salt and volcanic tuff. The programmes described ranged from national screening surveys on a broad, regional scale to detailed site specific investigations in underground research laboratories.
Contents: Keynote address; Programmes of international organizations; Site characterization programmes and methods; Repository design concepts, construction techniques and engineered barrier design; Characterization and acceptance of high level and alpha bearing wastes; Repository concepts for direct disposal of spent fuel; Developing, testing and validating repository performance assessment models; National and international programmes; Poster presentations.
