Research on electromagnetic radiation leakage from microwave ovens operating at 2.45 GHz.
Your microwave oven is one of the most powerful EMF sources in your home, operating at 2.5 gigahertz with enough radiofrequency energy to heat water molecules in food. While these appliances are designed with shielding to contain most emissions, no microwave is perfectly sealed, and EMF exposure occurs both from leakage during operation and from standing waves that can extend several feet from the unit.
