The relative absorption cross section of mankind exposed to nonionizing microwave radiation was determined using doll and sphere phantoms whose electrical properties simulated those of a human being. The investigation proceeded in three stages of increasing difficulty 1 theoretical and experimental study of homogeneous phantoms, having the electrical properties of muscle tissue 2 theoretical studies of two-layer phantoms, having the electrical properties of muscle tissue and subcutaneous fat and 3 ex trapolation to three-layer phantoms, having the electrical properties of muscle tissue, subcu taneous fat, and skin. The investigation at each stage resulted in certain generalizations which could be used as a guide to the investigations at the succeeding stage. In this way both the theoretical and experimental work necessary was simplified. The final stage involved a synthesis of all the previous work so that the relative absorption cross section of mankind could be predicted with confidence for the total frequency range from 400 to 10000 Mcs.
