The Use of Soil as an Expedient Countermeasure for Rural Fallout Shelters.
TL;DRAbstract
A series of SAM-CE Monte Carlo calculations has been performed to evaluate the effectiveness of the use of soil as an expedient countermeasure for rural fallout shelters. The shelters considered were a small wood frame house, a larger wood frame structure and the wing of a school building. Fallout exposures rates, at different locations within these structures, were determined for countermeasures involving various amounts of soil loaded on the roof and bermed against the outer walls. In all cases, the fallout field was assumed to be a pure 60Co source which was infinite in extent. The results show that the maximum countermeasure considered upgraded the rural structures considerably and provided protection factors in the 20-40 range.
