The effect of 120‐day exposure to a high‐intensity (80 kV/m), 60‐Hz electric field on histology of selected internal organs of Sprague‐Dawley rats was investigated. The organs examined were the pituitary, thymus, heart, lungs, liver, spleen, right and left adrenals, right and left kidneys, and right and left testes. Histological examination of 10‐micron tissue sections from randomly selected animals revealed no specific evidence of histopathologic differences between field‐exposed and sham‐exposed animals at the light microscopic level.
