We describe effect of whole body 900MHz Global System for Mobile communication-like electromagnetic field (GSM-EMF) exposure on microscopy of  vital organs of male Sprague–Dawley rats. Groups of 4 twenty adult male rats each were exposed to low, moderate, and high exposure by 1, 2 and 4 h. Controls were not exposed. The exposure was performed for 30 consecutive days. Heart, liver and  kidney tissue were fixed in 10% buffered formalin for histopathological examination. No toxic or behavioral changes were seen in any rats. However, necropsy revealed focal lesions in kidneys, subendocardial hemorrhage in 4 rats, 1 from each group and renal interstitial inflammation, hemorrhage, congestion in glumeruli and vessels. No lesions occurred in liver. Observations suggest GSM-EMF exposures at these intensities and duration may have induced lesions in heart, liver or kidney, but may not be EMF specific.
