Abstract : Near-in fallout as simulated by lutetium-177 labelled sand in size ranges 88-175 and 175-350 microns was dispersed over field crops and grazing animals and fed to sheep and cows. Initial retention and weathering half time were measured for alfalfa, corn, barley, bromegrass, sudan grass, sugarbeet tops and cows' backs. Residence times for the sand in sheep and cow digestive tracts were determined. (Author)
