Three hundred eighty-four young male rats were exposed to 45-Hz, vertical electric fields in nonmetallic cages, in an attempt to detect alteration of growth, food and water consumption, alterations in selected hematological and serum biochemical values, and pathological changes. 7 Three experiments were performed, each using six groups of 16 animals exposed to field strengths 0f 0, 2, 10, 20, 50, and 100 V/m (RMS). All variables were statistically analyzed ...
