Researchers exposed female rats to 2450 MHz microwave radiation (the same frequency as microwave ovens) and measured how it affected cell division in various organs. Higher power levels (32 mW/cm2) reduced cell division in ovaries and intestines, while lower levels (16 mW/cm2) actually increased it in ovaries. This suggests microwave exposure can disrupt normal cellular processes in reproductive and digestive tissues.
