The only consistently recognized biological effect of radiofrequency radiation in humans is heating. The ability of microwave ovens to heat food is one example of this effect of radiofrequency radiation. Radiofrequency exposure from cell phone use does cause heating to the area of the body where a cell phone or other device is held (e.g., the ear and head). However, it is not sufficient to measurably increase body temperature. There are no other clearly established effects on the human body from radiofrequency radiation.
The word radiation is, to the lay person, a scary word. Radiation is the stuff that 1960s school children were taught to climb under their desks to avoid, and what prompted Cold-War-terrified Americans to build backyard bomb shelters. Radiation is the stuff that leads meltdowns at nuclear power plants to contaminate the ocean and make land uninhabitable for hundreds of years.
1. Be careful what you share. “Use the same good sense about what you post from your phone as from a computer. Once they’re posted, text, photos, and video are tough to take back, can be copied and pasted elsewhere, and are up there pretty much forever. Think about the people in them (including you!). Reputations are at stake.” – Tips for Smart Cellphone Use, Connect Safely; Twitter: @ConnectSafely

Retrieved 2008-01-22. “Electromagnetic fields of all frequencies represent one of the most common and fastest growing environmental influences, about which anxiety and speculation are spreading. All populations are now exposed to varying degrees of EMF, and the levels will continue to increase as technology advances.”
It is useful to be aware of new health research regarding cell phone usage and cell phone radiation. The first cell phone call was made in 1985 and that phone cost $5,000 and weighed about 9 pounds. The change in size, weight and cost of devices today has probably led to over 50% of the human race owning a mobile device, the fastest growing technology on the planet.
