Wet and dry deposition and resuspension of AFCT/TFCT fuel process radionuclides. Technical progress report, 1 April 1978--30 June 1978
Size distribution of aerosol particles generated by acetone burners and pyrotechnic flares onboard Oregon State University's research aircraft were measured. These particles will be used as tracers in precipitation scavenging experiments. An outline is presented of the method proposed for measurement of precipitation efficiency; the method does not require measurements of the actual precipitation that has fallen on inaccessible, mountainous terrain. Sea salt particle size distributions were measured in the atmosphere's mixed layer, as a function of distance inland from the Pacific coast. These data are being analyzed in an attempt to deduce the dry deposition of submicron particles to forests. Flux and profile studies of dry deposition are progressing well. Data for resuspension from grass and from barren soil as functions of friction velocity, time since deposition, and ''weathering'' events are presented.
