In the first of two studies distributions of rates of EM energy absorption were observed in simulated biological bodies with embedded tumors. Part- and whole-body simulacra as irradiated by EM fields that ranged in frequency from 15 to 500 MHz exhibited differentially greater heating of tumors. Reduction of tumor conductivity resulted in enhancement of tumor heating. In the second study, a model of man was observed for induction of EM fields by 1 to 500-MHz energy. Greater rates of energy absorption occurred in regions of smaller cross sections and in tissues with lower conductivities.
