Are microwave ovens harmful as they are said to emit radiation?
if they leak radiation into environment than its harmful. thats why use oven of good brands and proper design. Working: Microwave ovens produce electromagnetic radiation of exactly the right wavelength to excite water molecules. When water molecules become excited, they heat up. Since most of our food contains a fair amount of water, we can heat up our food by selectively heating up the water inside the food. Microwave radiation also passes through glass and plastic, which allows it to travel through tupperware and heat up the food inside. However, microwave radiation does not penetrate very deep into the food itself, so if you put something big into the microwave oven for a short amount of time, it’ll be hot on the outside but still cool in the middle. To heat up something big like a turkey breast, the heat has to diffuse from the surface to the inside. Plan on putting at least a few minutes on the timer. Microwave ovens can definitely be harmful if used improperly. Microwave radiatio
