Fallout Simulant Development: Temperature Effects on the Sorption Reactions of Cesium on Feldspar, Clay, and Quartz

摘要

Procedures were developed for the preparation of synthetic fallout with which to study the availability of cesium. Mineral particles were tagged with Cs-137 and heated to a series of temperatures including 1500C. The effect of these thermal treatments on the availability of cesium was evaluated by leaching in 0.1N HCl. Surface adsorption effects were measured on particles that were not heated. The reproducibility of the results obtained by those procedures was tested by preparing a batch of synthetic fallout with specified properties for studies of the uptake and retention of cesium by animals.
