MICROWAVES

WHAT ARE MICROWAVES?

Microwaves are a type of electromagnetic radiation, as are radio waves, ultraviolet radiation, X-rays and gamma-rays. Microwaves have a range of applications, including communications, radar and, perhaps best known by most people, cooking.

HEALTH IMPACTS?

Microwaves Can Change Your Heart Rate

Microwaves can produce effects on your body instantly due to the 2.4 GHz radiation — the frequency of radiation emitted by microwave ovens. A

study

conducted by Dr. Magda Havas of Trent University found the levels of radiation emitted by a microwave affect both heart rate and heart rate variability. These levels are within federal safety guidelines but tend to cause immediate and dramatic changes in heart rate. If you experience irregular heart beat or any chest pain and regularly eat microwaved food, it might be best to discontinue use.



Microwave ovens are highly versatile. They can be used to cook, defrost and re-heat foods and beverages. Microwave ovens use high frequency electromagnetic waves. These high frequency waves cause molecules of liquid naturally present in your food to vibrate. This friction is what heats and cooks your food. Microwaves heat and cook your food from the inside out rather than going through your food, from the outside in, which takes longer.

EVERYDAY APPLICATIONS?

Microwaves are also in cellular phones, telephones, telegraphs, television, and satellites. They are useful in communication because they easily penetrate the earth's atmosphere.

Microwaves are primarily used in medical cases as an alternative to surgery. For example an enlarged prostate. Instead of surgically removing the problematic organ, doctors can use microwaves to heat op the enlarging tissue of the prostate.

Microwaves in this field are primarily used for clean up. They can be used to decrease air pollutants, sanitize hospital waste, enhance dry cleaning solvents, and clean up polluted soil.

The above link is an article about the radiation of microwaves and other jobs the microwave can do. Microwaves are a form of electromagnetic radiation; that is, they are waves of electrical and magnetic energy moving together through space. Electromagnetic radiation ranges from the energetic x rays to the less-energetic radiofrequency waves used in broadcasting. Microwaves should not be confused with x rays, which are more powerful.
