Argentina (Continued) G/R.84 MUTATIONS IN BARLEY INDUCED BY FORMALDEHYDE A report of experiments on the induction of mutations at a number of loci in barley by formaldehyde. G/R.85 SPONTANEOUS MUTATIONSIN BARLEY A report of experiments on spontaneous mutations at a number of loci in barley. G/R.86 A STUDY OF RADIOACTIVE FALLOUT IN THE ARGENTINE REPUBLIC Describes the methods used in the Argentine Republic for fallout collection and measurement. Value for Sr* and total beta activity are given for the first two months of 1957. G/R.87 A RESEARCH PROGRAMME IN THE ARGENTINE ON THE GENETIC INFLUENCE IN THE PLANTS OF THE IONIZING AND ULTRA-VIOLET RADIATION A brief summary of projected research in Argentina on the genetic effects of ionizing and ultra-violet irradiations of plants, comprising both surveys of areas of high natural background and a broad range of laboratory experiments. G/R.88 PROGRAMMEOF PHYSICAL OCEANOGRAPHY FOR THE INTERNATIONAL GEOPHYSICAL YEAR G/R.89 INFORMATION ON THE GENERAL PROGRAMME TO BE DEVELOPED IN THE ARGENTINE ON ITEMS OF INTEREST TO THE SCIENTIFIC COMMITTEE ON THE EFFECTS OF ATOMIC RADIATION A brief general survey of Argentina research activities related to the effects and levels of ionizing radiations. G/R.127 CALCIUM AND POTASSIUM CONTENT OF FOODSTUFFS IN THE ARGENTINE REPUBLIC G/R.154 NORMAL CALCIUM CONTENTOF SAN JUAN WINES G/R.157 RADIOACTIVE FALLOUT FROM THE ATMOSPHERE IN THE ARGENTINE REPUBLIC DURING 1957 Includes tables of results for first three-quarters of 1957. Total activity and Sr* content is measured. : Australia G/R.29 Report consisting of 6 parts, as follows: (PART I) HUMAN GENETICS Report gives recommendation as to the kind of human mutations which could be scored: several dominant autosomal genes should be investigated (gives list of such genetical abnormalities). PART (0) PLANT GENETICS Gives plan of research to be organized. (PART III) RADIOBIOLOGICAL UNIT IN THE UNIVERSITY OF ADELAIDE To be established. (PART IV) NATURAL RADIATION BACKGROUND AND ENVIRONMENTAL CONTAMINATION Describes future organization of investigations on natural radiation background and contamination; radioactivity of food will be determined. (PART V) OCCUPATIONAL EXPOSURE IN AUSTRALIA Describes monitoring system in application since 1940 and summarizes observations done by the use of film badges (gives statement of per centof personnel having received a specified per cent of the permissible dosage). 174
