Construction plans, details and bill of materials for a 6 person family shelter are presented. Radiation shielding with PF 100 is provided by masonry walls 1 ft to 8-in.-thick and a roof composed of 17 to 20 inches of gravel fill sandwiched between two concrete slabs 4 12- and 2 12 - in. thick. The shelter design was developed for construction by a contractor. It is particularly suitable for locations where below ground, including basement, structures are not feasible or an above-ground building is desired for non- shelter use. Alternate designs are discussed which will improve andor reduce the cost of the shelter. A manual or manual-electric blower, electrical wiring, furnishings and shelter supplies are required to complete the shelter. Dual purpose uses such as general storage, tool shed, garden supply storage or workshop were considered in the design and evaluation of the shelter.
