India (Continued) G/R.166 MEASUREMENTS ON THE RADIATION FIELDS IN THE MONAZITE AREAS OF KERALAIN INDIA Presents results of measurements in the monazite area with high thorium content. As this area is one of the most densely populated areas in the world, the study of the relation between high level radiation background and eventual biological effect would be of great value. The average dose is 1500 mrad per year, exceeding 3 times the maximum permissible dose. : International Commission on Radiological Protection and International Commission on Radiological Units and Measurements G/R.117 EXPOSURE OF MAN TO IONIZING RADIATION ARISING FROM MEDICAL PROCEDURES Gives a survey of the present exposure of the gonads due to X-ray diagnostic procedures. Some 85% of the diagnostic dose arises from 6 to 7 types of examinations, which are discussed separately. Estimates of the genetically significant dose are given for some countries. It is recommended that the basic studies be extended and that more detailed analysis be obtained through sampling procedures rather than through the systematic recording of the radiation received by every member of the population. Methods for dose reduction are discussed. Italy G/R.134 REPORT ON GENETICS 1950 -1957—A BRIEF REPORT ON THE RESEARCH WORK DONE IN THE FIELD OF GENETICSIN ITALY Extensive notes reporting relevant research work in the field of genetics carried out in Italy during the period 1950-1957. G/R.195 DATA ON RADIOACTIVE FALLOUT COLLECTED IN ITALY (1956, 1957, 1958) Japan G/R.4 Report consisting of 8 parts, as follow: PART 1. RESEARCHES ON THE EFFECTS OF THE H-BOMB EXPLOSION AT BIKINI ATOLL 1954 ON ANIMAL INDUSTRY AND SERICULTURE IN JAPAN Gives negative results of analysis by absorption method of radioactivity in milk, eggs, and agricultural products following the Bikini explosions of May 1954. Related experimental feedings of animals with radioactive ashes were analyzed chemically. PART 2. THE RADIOACTIVE CONTAMINATION OF AGRICULTURAL CROPS IN JAPAN Gives results of soil and crop analyses for total radioactivity before and after the May 1954 Bikini explosions, after subtraction of kK’? content, and with some radiochemical analysis. Radioactivity after the explosion was detected in soil, crops, and other vegetation which are distributed all over Japan. The possible route of contamination is discussed. PART 3. A PRELIMINARY REPORT OF RECOMMENDATIONS ON THE MODERN METHODS OF ESTIMATING THE BIOLOGICAL ACTIVITY OF SMALL RADIATION DOSE Several current hematological findings in Japan are summarized and discussed. 181
