Abstract : Simulated near-in fallout experiments have been conducted using batches of 88-175u and 175-350u sand labelled with the low energy gamma-ray emitter, 177Lu (6.7 day half-life). Targets of field releases were alfalfa, pasture grass, field corn and grazing cows. Initial retention was determined by comparison with disc impactors and retention was measured as a function of time. Controlled deposition experiments were performed in a test chamber on corn, barley, tomatoes, beans and carrot plants. (Author)
