[en] This volume represents the fourth annual report on the results obtained under the Agency's research contract programme. During the short life of this programme, which is not quite six years old, a total investment of more than three million dollars has been made to support research in selected fields at institutes in 50 Member States. Extensive summaries are presented herein for all final reports relating to contracts which were completed during 1963. As it is the policy of the Agency to encourage publication in the open scientific literature of the results of work done under research contracts, a number of papers have also appeared in the appropriate journals - the Agency having been notified of 75 such publications in 1963. A complete list of references to these is given at the end of this report. The scientific data presented in the summaries of course remain the responsibility of the contractor. The Agency, however, is responsible for any additional observations. The reports presented are related to research in the field of radioactive waste management and environmental sciences; health physics and radiation protection; radiobiology; nuclear reactors physics and nuclear fuels; radioisotope applications in agriculture and medicine
[en] The fate of radionuclides introduced into fresh water will be influenced not only by the volume of the water available for dilution, but also by a number of other physical, chemical and biological factors like replacement of the water mass, turbulence and location of the currents, chemical composition of effluent and receiving water, suspended materials, thermal characteristics and density differences, precipitation and sedimentation, ion-exchange and adsorption, incorporation by living organisms, and special features characteristics of the type of water body involved, i.e. whether stream, lake, estuary or sub-surface.
[en] During the period in which the Agency's research programme has been operative, nearly 150 research contracts have been placed with institutions in 35 Member States. While considerable emphasis was placed initially on research of a more fundamental nature - as reflected by the summaries presented herein of work under contracts awarded in the early stages of the programme - recent policy has shifted the major emphasis toward research of a practical nature, as the results of this type of research are likely to be of more immediate interest to Member States, and particularly to the developing nations. In every case, the summary of the contractor's final report has been prepared by that member of the Agency's scientific staff who has been closely connected with that particular subject of research. Thus, the scientific data reported in the summary remain the responsibility of the contractor, the Agency being responsible for any additional observations. The reports in the field of Radioactive waste management and environmental research included are: Research Contract No.20. Studies in the uptake of radioisotopes by edible marine products; Research Contract No. 33, Behaviour of fission products in soil; Research Contract No.100, Ionic interaction near clay surfaces. Reports dealing with Health physics and radiation protection presented are: Research Contract No.14, The effect of radiation on plant cells and its modification with protective substances; Research Contract No.32, Determination of the enrichment factors of calcium isotopes on ion exchange resins and the investigation of the various systems of electrolytic separation; Research Contract No. 53, Selection of sulphydryl compounds for radiation protection, using a new microbiological method; Research Contract No. 79, A study of the uptake of radioactive calcium in the skeleton. Reports related to Radiobiology are: Research Contract No.11, Genetical investigations on the effect of ionizing radiation on human cells grown in vitro; Research Contract No.15, Chemically induced metabolic modifications of cells susceptible to modify the sensitivity of microorganisms to ionizing radiations; Research Contract No.17, Action of ionizing radiations on pathogenic human and animal virus; effects on virulence and antigenic vaccinogen activity; Research Contract No.29, Study of the radiosensitivity and isolation of radioresistant strains of Lactobacillus; Research Contract No.35, A study of the primary biochemical lesions produced by ionizing radiations in mammalian tissues; Research Contract No.52, Immediate effects of radiation on the mechanical and electrical activities of autonomous isolated organs when submitted to perfusion with radioactive Rb-86 or to low doses of external radiation; Research Contract No.86, The influence of radiation and radiomimetic chemicals on genetic transduction in Pseudomonas aeruginosa; Research Contract No. 96, An attempt to correlate quantitatively the changes in permeability of mammalian muscle cells with the radiation dose. Report related to Reactor research presented is: Research Contract No.116, Metallographic study of the transformation of gamma- phase into alpha i- delta or gamma prime phases in low molybdenum-uranium alloys. Reports in the field of Radioisotope applications in agriculture and in medicine presented are: Research Contract No.21, Studies on the use of radioactive isotopes for fertilizer evaluation; Research Contract No.27, Application of radiation-induced mutations to plant breeding; Research Contract No.24, Red cell survival studies with radioisotopes In Thalassaemia Haemoglobin-E and Thalassaemia Haemoglobin-H disease; Research Contract No.89, Study of the effects of malnutrition on albumin metabolism in man
[en] This volume is the fifth annual report and presents full summaries of 26 final reports from contracts, sponsored under the Agency's Research Contract Programme, which were completed during 1964. In addition to the summaries describing more general work in 'Health physics and radiation protection', seven reports are included which describe work done under the Agency's first highly-coordinated programme in which various applications of Ca-47 in the fields of medicine and health physics were explored. In every case the summary of the contractor's final report has been prepared by that member of the Agency's scientific staff who has been most closely connected with the particular branch of research concerned. The scientific data are the responsibility of the contractor, though the Agency is responsible for any additional observations. The reports presented are related to research in the field of radioactive waste management and environmental sciences; health physics and radiation protection; radiobiology; safeguards methods; nuclear reactors physics and nuclear fuels; radioisotope applications in agriculture and medicine
