Answer 1

Dr. Martin Blank, from the Department of Physiology and Cellular Biophysics at Columbia University, warns:

Putting it bluntly (cellphones) are damaging the living cells in our bodies and killing many of us prematurely… We have created something that is harming us, and it is getting out of control. Before Edison’s light bulb there was very little electromagnetic radiation in our environment. The levels today are very many times higher than natural background levels, and are growing rapidly because of all the new devices that emit this radiation.
