"Feasibility of citizen construction of expedient fallout shelters final report" . "Seventeen families attempted to build seven types of earth-covered expedient fallout shelters while guided only by one-page shelter-building instructions prepared by DCPA. Within 48 hours of starting, all but one family succeeded in building a shelter affording good fallout protection. Families spent an average of 88 minutes trying to interpret their one page of instructions. The abbreviated DCPA instructions for building an expedient shelter-ventilating pump -- essential for the multiday occupancy of below-ground shelters, except in cold weather -- were followed successfully by only four out of nine families. This report makes numerous recommendations for improving all the instructions. (Author)."@en . . "Feasibility studies." . .
