France (Continued) Suggests the improvementof the radiological techniques and certain protective measures for decreasing of gonad dose from radiography. G/R.194 GONAD DOSES IN RADIODIAGNOSIS Summarizes the systematic study on the gonad dose due to diagnostic examination by means of X-rays. G/R.211 ETUDE DE LA DOSE GONADE, LORS DES EXAMENS RADIO-PHOTOGRAPHIQUES SYSTEMATIQUES. NOTE PRELIMINAIRE CONCERNANT EXCLUSIVEMENT L’IRRADIATION DES GONADES MALES. Measurementof the gonad dose resulting in males from systematic standardized X-ray examination of the chest indicate that the exposure is very low. An average of 9 mrem for a period of 30 years is computed. The dose to the lungs is discussed with relation to the increase in frequency of lung cancer. G/R.212 DETERMINATION DU RAPPORT DOSE-ABSORBEE/DOSE D’EXPOSITION DANS L’OS ET LE MUSELE PAR LA METHODE DES GAZ EQUIVALENTS. PRINCIPE DE LA METHODS ET RESULTATS PRELIMINAIRES Describes the method for determination of the dose absorbed in various tissues using ionization chambers filled with gas mixtures of equivalent density. G/R.213 LA RESTAURATION CONSECUTIVE A L’ACTION DES RADIATIONS IONISANTES The authors first discuss the problem of recovery which they consider hypothetically. They attempt to show that it is a phenomenon which, though appearing very complex at first glance, can be simplified by relating the recovery to a definite effect. They contribute a series of experiments showing that recovery is a very general phenomenon, common to all living things, and related to the metabolic activity of living matter. They contribute a new method of experimental analysis which greatly facilitates interpretation of the results. They believe that the study of recovery should be developed on a much larger scale. Hungary G/R.25 UNUSUAL RADIOACTIVITY OBSERVED IN THE ATMOSPHERIC PRECIPITATION IN DEBRECEN (HUNGARY) BETWEEN 22 APRIL-—31 DECEMBER 1952 Describes methods and discusses results of measurements oftotal beta activity of fallout at Debrecen, April—December 1952. India 4/R.32 PROCEDURE USED IN INDIA FOR COLLECTION OF FALLOUT SAMPLES AND SOME DATA ON FALLOUT RECORDED IN 1956 Describes methods for measurements of airborne activity by filtration, and of deposited fallout with daily and monthly collection. The information includes tables giving results. G/R.33 EXTERNAL RADIATION DOSE RECEIVED BY THE INHABITANTS OF MONOZITE AREAS OF TRAVANCORE-COCHIN, INDIA Contains results of a survey to measure the radiation level of the Indian state of Travancore. The radiation level due to gammarays at about 3 feet above the ground level ranges from 6,000 to 100 mrad/year, approximately. The main contributors are thorium and its decay products. 180
