The design and performance of a fallout-tested manned shelter station and its suitability as a single-family shelter /

Design details, cost analysis and performance characteristics are presented for small, partially-underground fallout shelters utilized as manned stations during a nuclear weapon effects test. Four men occupied each shelter and operated radiation measurements and fallout collection instruments. Two types of shelters were designed to withstand predicted over-pressures: type I, 1-psi overpressure and type II, 5-psi overpressure. The basic structure consisted of an 8-ft diameter, 10-ft long, 12-gage corrugated steel, multi-plate pipe. A steel entranceway with two right-angle turns provided access to the basic structure. Depending on the amount of soil backfill, fallout gamma radiation protection factors up to 470,000 were obtained. The overall performance of the shelters under the conditions experienced was excellent. Shelters of this type have application not only for use as manned stations in nuclear weapon testing and can be adapted for use in residential areas as single-family fallout shelters.Cover title."23 April 1963."Includes bibliographical references (pages 34-35).Design details, cost analysis and performance characteristics are presented for small, partially-underground fallout shelters utilized as manned stations during a nuclear weapon effects test.
