The behavior};of Cs-137 has proved to be an intractable problem that has major implications for the risks associated with transporting and processing high-level nuclear wastes in the U.S. Various proposed soil treatment strategies for Bikini are discussed, including ion-exchange treatments and competing-ion strategies. No fully satisfactory treatment currently exists and the problems and prospects of cleaning up after a major nuclear waste spill are presented.

Greenhouse experiment in three volcanic ash soils ANALYTIC AUTHOR/AFFIL Pino N, I.; Casas G, L. [Comision Chilena de Energia PAGE RANGE PUB. DATE (YYMMDD) LIMITATION CODE ABSTRACT Nuclear, 37-40 890400 UNL Santiago (Chile) ] With the aim to evaluate the behaviour of phosphoric rock in regard to the sorption capacity from three volcanic ash soils, a greenhouse trial was carried out. The isotopic dilution method with triple superphosphate labeled P32 (TSP-32) was used. concentrated or not. (author). Total dry matter, P total was determined by colorimetry and the liquid scintillation method for P32 was used. The evaluation of the rock was measured through different isotopical parameters such as A value and P derived from the rock. The behaviour of this material was affected by the different properties of the soils mainly on account of the diverse sorption capacity of them giving an inverse relation among sorption and effectiveness of the rock. The results showed a higher efficiency of TSP for the three soils compared with the phosphoric rock either KEYWORDS PHOSPHORUS 32/labelled compounds ;PHOSPHORUS 32/radionuclide migration ;PHOSPHORUS 32/soils ; SOILS/greenhouse project ;SOILS/isotope dilution ; SOILS/superphosphates ;ABSORPTION SPECTROSCOPY; ADSORPTION; CHILE; IGNEOUS ROCKS; LIQUID SCINTILLATION DETECTORS ; SOILS; SUPERPHOSPHATES 90034b9
