Long-Term 2450-MHz CW Microwave Irradiation of Rabbits: Methodology and Evaluation of Ocular and Physiologic Effects

Abstract
In order to assess the biological effects of long-term microwave radiation, special exposure systems were developed and used to expose four rabbits to 10-mW/cm2 microwave radiation (maximum 17 W/kg SAR) for 23 h per day for 180 days. Comparisons with four sham-exposed rabbits revealed no significant effects in terms of eyes, body mass, urinary output, rectal temperature, hematocrit, hemoglobin, white cell count, and basic blood-coagulation studies. After the experiment, the animals were sent to the National Institute of Environmental Health Sciences for additional analyses which revealed biochemical effects as reported in a companion paper in this issue.
