During World War II, two scientists invented a tube that produced microwaves called the magnetron. Combining the magnetrons within Britain’s radar system, the microwaves were able to find Nazi warplanes on their mission to bomb the British Isles.
By accident, Percy LeBaron Spencer of the Raytheon Company (several years later) discovered that microwaves also cook food. He found that radar waves had melted a candy bar in his pocket. The first microwave oven to go on the market, called the Radar Range was as large and heavy as a refrigerator.
According to a growing body of research, microwave ovens are dangerous to our health.
1How do microwave ovens heat/cook our food?
Alternating currents force atoms to reverse their polarity. This creates friction and vibrates the water inside of the food molecules causing the food to heat up.
How are microwave ovens dangerous? Inside of your microwave there are 2.45 billion hertz which is fine, until the seal on your microwave door ages and begins to leak. The frequency amount shown to harm the human body is 10 hertz. Be cautious and never stand near an operating microwave. You won’t know your body is being harmed by the leak until the damage is already done.
