Discussion of the effects of nuclear weapons and consequent radiation fallout precedes justification of the need for fallout shelters. Competition for the design of an elementary school with a population of 300-500 and an emergency population of 600-1000 is then described. Criteria and requirements are detailed. The winning entries illustrate that--(1) shelter capability can be incorporated in a school with no interference to the educational process, (2) cost increase for shelter capability is reasonable, (3) dual use shelters need not adversely affect the esthetics nor the function of a school, and (4) principles of shelter integration with educational buildings are applicable to other building types. The seven winning entries are described and illustrated through plan and perspective views. (MH)
