Radiological Physics Division Semiannual Report for January Through June 1957

ABS>Progress is reported in the following studies: the autoradiographic mapping of the deposition of Ca/sup 45/ in cortical bone in dogs; measurement of fission-product activity present in soil; factors affecting the performance of ionization chambers; calibration tests on the dibutyl phosphate method of isolating Th/sup 228/ from solutions of ashed bone; microradiographic demonstration of changes in mineral density in dog bones; radiometric determination of radon in bone and in the atmosphere; changes produced in xylene by exposure to massive doses of Co/sup 60/ gamma radiation; applications of the human spectrometer in in vivo measurements of Cs/sup 137/ build-up in humans; determinations of Cs/sup 137/ atmospheric content as a function of time; development of a tracer method using K/sup 42/ for measurement of exchangeable potassium in humans; determinations of the radium body burdens in fornner dial painters; and the atmospheric diffusion of stack particles. A meteorological model towing tank is described which was constructed as an alternative to a wind tunnel for model studies of atmospheric turbulent diffusion. Preliminary studies employing the apparatus are described. (For preceding period see ANL-5679.) (C.H.)
