Research efforts have been focused on the impacts of new technology on human health. One of the leading new factors is the technology of cell phones, which is predicted to have more than 1.3 billion worldwide users by the 2005. Cell phones have been of the fastest growing industries. Today most people have portable phones in their home, and/or cell phones. Theses devices are connecting people in convenient ways as their cost declines with the expand use. Heath effects from phones and other communication devices is quickly becoming the focus of a great deal of research. It has been known that the subtle effect of light and colors with the human result in eyesight and that sound wave is energy transformed by the ear so we can hear. Tests have been done by the Microwave institute of Zhejiang Medical University that show the effects of exposure to environmental electromagnetic fields (EMFs) EMFs are used in the cell phones we use today. Visual reaction time was prolonged and the scores of short-term memory tests were lowered in high intensity exposure groups. These test also showed that the energy fields could affect the central nervous system and immune system. Chronic exposure causes changes in some physiological parameters.

Pregnant woman have been warned to be careful and wary of using cell phones after research showed radiation produced by the devices caused defects in chicken embryos. Researchers still urge pregnant women to use cell phones until all risks are properly assessed. British mobile phone specialist Roger Coghill said the findings were " enormously worrying". Research has also been done on the possible effects of radio frequency radiation on prenatal development through the investigation in mice.

Australian research has found one the strongest links between cell phones and cancer. Mice were exposed to cell phone radiation. Over periods of 9 to 18 months, the exposed mice had twice the rate of tumors as unexposed mice. The industry defense is...
