Australia (Continued) (PART VI) HEALTH AND SAFETY PRECAUTIONS IN URANIUM MINING AND MILLING IN AUSTRALIA Describes health and safety precautions in uranium mining and milling. Austria G/R.19 INFORMATION PREPARED BY THE AUSTRIAN GOVERNMENT RELATING TO THE EFFECTS OF ATOMIC RADIATION Describes radioactive warm springs at Bad Gastein, giving activity levels in water and air. Outlines wide scope of biological and instrumental research at Gastein Institute. G/R.102 RADIOLOGICAL DATA. DEMOGRAPHIC DATA Contains data on RBE dose rate in the gonad due to both natural and artificial sources. Demographic data of the whole population and of special groups are given. Belgium G/R.3 PRELIMINARY REPORT ON MODERN METHODS FOR THE EVALUATION OF THE BIOLOGICAL EFFECTS OF SMALL DOSES OF EXTERNAL RADIATION OR ABSORBED RADIOACTIVE MATERIALS Concludes that the most hopeful measurements are those of: (1) DNases and cathepsins in plasma and urine; (2) DNA synthesis in vitro by bone marrow or biopsy specimens; (3) Platelet counts; (4) Antibody synthesis, and that the Committee should re-emphasize the need of appropriate fundamental research in radiobiology. G/R.26 REPORT CONSISTING OF FIVE PARTS 1. Gives results of clinical observations of patients treated with X-rays, Ra or 1"! and of persons occupationally exposed. 2. Gives results of studies relating to: the medical and physical control of persons occupationally exposed; the absorbing materials; and the radioactive contamination of the atmosphere. 3. Considers preventive or curative methods of syndromes of acute irradiation. States results of doses received by the occupationally exposed personnel of the Institut du cancer of Louvain, Belgium, and of hematological examinations of them. 4. Describes methods for measuring the radioactivity in rain and surface waters. Gives results of measures of radioactivity in rain waters. 5. Describes method for measuring the radioactivity of atmospheric dust by continuous filtering of air. G/R.78 INFORMATION IN 8 PARTS ON HUMAN GENETICS SUBMITTED BY BELGIUM Contains the Belgian memorandum on humangenetics prepared for the Geneva meeting in April 1957 and a preliminary report on radioactive regions of Katanga (Belgian Congo). Besides this several reprints of Belgian contributions to radiobiology are presented. The topics included are: (1) Steroid metabolism in irradiated rat; (2) Endocrine response of irradiated animals studied by intraocular grafting; (3) Doses and hazards due to medical radiology; (4) Metabolism and toxicity of cystamine in the rat. Part 1. Current uncertainties in the field of human genetics. Part 2. A preliminary survey of vegetation and its radioactive content in the Katanga area. Part 3. Influence of irradiation on the blood level of 17-hydroxycorticosteroids during the 24 hours following irradiation. 175 ieey wegen
