Fallout Simulant Development. Leaching of Fission Products from Nevada Fallout and Summary of Synthetic Fallout Production.
Abstract
Long-term leaching studies were conducted with field samples collected at SHASTA, SMALL BOY, JOHNIE BOY, and SEDAN. Fallout from each of these nuclear events was leached by 0.1N HCl (to represent stomach acid) and distilled water. The leaching mechanism for the removal of eight-year-old fission products from SMALL BOY fallout by 0.1N HCl appears to be controlled by a sorption reaction for a few days, after which it is controlled by a diffusion process. Leaching of SMALL BOY fallout by 0.1N HCl removed 60% of the activity from large particles and 30% from small particles. Leaching by water removed only a few percent of the activity. Generally, less than 10% of the activity was removed from SHASTA, JOHNIE BOY, or SEDAN fallout by either 0.1N HCl or water.
