Dr. K C Yee has been a researcher in the area of microwave.
Even in the early 70s, long before cell phones are even known, Dr K C Yee started to research in the area of microwave, and its effect on animal health. When K C Yee started in this area, there was already concerns of electrical power transmission line and health. However, power transmission lines while has much higher power, operates at a much lower frequency compared with microwave communication towers.
so after more than 30 years of research, Dr K C Yee feels that while the effect of microwave transmission towers on human health is not conclusively known, he suggests to stay away from the microwave towers if at all possible.
