Behind the Scenes

The Head of Research at Lund University, Sweden, Professor Leif Salford said, "The voluntary exposure of the brain to microwaves from hand-held mobile phones... [is] the largest human biological experiment ever."

Mobile phones, digital wireless systems, and communication networks produce electromagnetic radiation in the microwave range.  This also includes occupational contact such as, traffic radar devices which expose police officers and many others daily.

The potential health effects of electric and magnetic fields are controversial. They are the subject of intense and ongoing research.  General health effects explore potential carcinogenic, reproductive and neurologic results.


Microwave radiation is an integral part of society today.  Exposure sources involve the growing number of radar traffic devices, wireless communications with cellular phones, radio transmission, and magnetic resonance imaging (MRI).

We have known about the exposure to radiation in the form of X-rays increasing the risk of cancer for decades.  However, there is no scientific consensus after reviewing the evidence that microwave radiation boosts the risk of getting cancer.  As a matter of fact, microwave radiation is not even enough to increase body temperature. In addition, there are no clearly established effects on the body.

Microwave radiation has shown to be a consistent and reliable energy source for heat. We use is for its ability to heat food, as in the microwave ovens in our kitchens.  Otherwise, the health effects are inconclusive. Two small studies looked at glucose metabolism and microwave radiation. One study showed an increase in glucose metabolism the other found a reduction!


Excess exposure to microwave radiation may result in a rise of free radicals in the body. Free radicals are produced by a natural body process as well as from the environment. They are electron atoms that are no longer paired with another atom. They roam free in the body to bind to oxygen. According to the free radical theory of aging, as these free radicals pile up there is cell damage over time.  Contributing factors are lifestyle choices including diet, stress, smoking, alcohol, exercise, inflammation, drugs, exposure to sunlight, and pollution. They all play a role in free radical formation.

There are nutritional supplements that have been shown to decrease the amount free radicals in the body. They are called anti-oxidants.  They appear to help the body protect itself by preventing the breakdown of DNA in the cells. Some anti-oxidant supplements are:

  • Catalase
  • Glutathione,
  • Melatonin
  • Zinc may be selective to the eye and blood
  • Gingko Biloba is a herb to protect the brain, eyes, and kidneys
  • Bilberry extract may preserve vision and reduce damage to the eyes.

With the estimated, worldwide cell phone users in the billions, scientists fear that there is not enough known about microwave exposure and the risks.  The basic premise of common sense and everything in moderation is applicable. According to the World Health Organization (WHO), they advise a "precautionary principle". Limit exposure, not only to radiation sources and potentially worrying information as well. Too much information adds to our stress!
