A model for radiofrequency electromagnetic field predictions at outdoor and indoor locations in the context of epidemiological research.

abstract：:Measurements have been made of vector current densities induced by vertical, uniform, 60-Hz electric fields in the torsos of homogeneous models of swine and rats. The observed data were a strong function of the five grounding configurations invested: all four feet grounded, only front feet grounded, only rear feet gro...
