RADIOLOGICAL PHYSICS DIVISION SEMIANNUAL REPORT FOR JULY THROUGH DECEMBER 1957
Progress is reported in the following studies: effects of various doses of gamma radiation on the light absorbance of aerated and air-free samples of xylenes the design of a light piping system for a scintillation spectrometer; the development of a simple source of monoenergetic fast neutrons and the possibility of using a spherical moderator to produce a roughly monochromatic distribution of neutrons from a source of monochromatic neutrons of a higher energy; calculation of the body retention and elimination of Ra/sup 228/ and Ra/sup 224/ following a single injection of Th/sup 232/; the analysis of gamma-ray spectra by the method of least squares; application of a microradiographic technique in determinations of the mineral density of human bones at various ages and density values for old bone and new growth in bones from man, dogs, mice, cows, rabbits, and rats; the bone deposition of Ca/sup 45/ following injection in dogs; determination of the natural Ra/sup 226/ content of 200 water samples from Illinois municipal water supplies; attempts to estimate the fraction of the stratospheric Sr/sup 90/ in the total Sr/sup 90/ transported to the ground by rain by observing variations in the relative amounts of Sr/sup 89/, Sr/sup 90/, and Ba/sup 140/ in water from a series of rainfalls; the monitoring of the atmosphere for fall-outs design of a transportable gamma-ray spectrometers soil temperature studies; the operation of an automatic data processing system for use with the soil temperature measurementss measurements of atmospheric radon; wind-tunnel studies on dispersal patterns of stack gases; and application of a meteorological model towing tank for studies of turbulent diffusion in the atmosphere. A list is included of articles published and accepted for publication during the period. (For preceding period see AHL-5755.) (C.H.)
