In this article, Dr Andrew Goldsworthy (a retired engineering lecturer from Imperial College London) explains how weak electromagnetic fields from cell phones, cordless phones and WiFi can have serious effects on our health. These include damage to glands resulting in obesity and related disorders, chronic fatigue, autism, increases in allergies and multiple chemical sensitivities, early dementia, DNA damage, loss of fertility and cancer.
All this happens at levels of radiation that our governments and the cell phone companies tell us are safe because the radiation is too weak to cause significant heating. This is the only criterion that they use to assess safety. In fact, the direct electrical effect on our cells, organs and tissues do far more damage at to us at energy levels that may be hundreds or thousands of times lower than those that cause significant heating. These are termed non-thermal effects and our governments are doing nothing to protect us from them.
