United Kingdom (Continued) G/R.152 THE ANALYSIS OF LOW LEVEL GAMMA-RAY ACTIVITY BY SCINTILLATION SPECTROMETRY The application of gamma-ray spectrometry enables measurementof the gamma-activity of 10~'! curies or less. G/R.167 MEASUREMENTSOF Cs?" IN HUMAN BEINGSIN THE UNITED KINGDOM 1956/1957 Describes the method of determining the Cs 137 content in the gamma-ray spectrometry. The average present value is 34.0 = 7.6 uc per g potassium. human body using G/R.170 THE DISPOSAL OF RADIOACTIVE WASTE TO THE SEA DURING 1956 BY THE UNITED KINGDOM ATOMIC ENERGY AUTHORITY Summarizes the discharges of liquid radioactive wastes to the coastal sea from Windscale Works during 1956. The results of monitoring indicate that the average activity of the samples remains well below the permissible level. G/R.171 A SUMMARYOF THE BIOLOGICAL INVESTIGATIONS OF THE DISCHARGES OF AQUEOUS RADIOACTIVE WASTE TO THE SEA FROM WINDSCALE WORKS, SELLAFIELD, CUMBERLAND Summarizes the results of preliminary hydrographic and biological studies and of regular monitoring of the marine environment in the period 1952-1956. About 2,500 curies of radioactive wastes monthly has been discharged during this period. Due to the favorable local conditions, the upper limit for safe liquidation is determined to be more than 45,000 curies per month. United States of America G/R.1 THE BIOLOGICAL EFFECTS OF ATOMIC RADIATION Summarizes general survey in which committees of experts coveredthe following subjects: genetics; pathology; meteorology; oceanography and fisheries, agriculture and food supplies; disposal and disposers of radioactive wastes. G/R.7 RADIOACTIVE FALLOUT THROUGH SEPTEMBER 1955 Summarizes analysis of daily samples obtained up to end of September 1955 from 26 stations in United States and 62 elsewhere by gummed film method calibrated against collection in high walled pots (see A/AC.82/INF.1). Cumulative deposition of mixed fission products, integral gamma doses and Sr” deposits are calculated and compared with other findings, including Sr® content of soils and milk. G/R.11 PATHOLOGIC EFFECTS OF ATOMIC RADIATION Present knowledge of the pathological (non-hereditary) effects of radiation are surveyed extensively by a committee. Includes separate sections by sub-committees or individual members on: acute and long-term hematological effects; toxicity of internal emitters; acute and chronic effects of radioactive particles on the respiratory tract, delayed effects of ionizing radiations from external sources; effects of radiation on the embryo andfoetus; radiation in a disturbed environment; effects of irradiation of the nervous system; radiation effects on endocrine organs. G/R.21 PROJECT SUNSHINE BULLETIN NO. 12 Presents and discusses results of Sr® analysis since 1 December 1955. Includes Sr® concentration in human and animal bones, animal products, vegetation, soil, precipitation, other water, and air. 197
