Radiation from cell phones is harmful and should be minimized.

Some people worry that the radio frequency energy emitted by cell phones will result in cancer or other severe health risks. The FDA thinks that, at or below the radio frequency exposure limitations established by the FCC, the weight of scientific evidence does not link exposure to radio frequency energy from cell phone use with any health issues. This is based on an examination of the information that is currently available.

Low-level radio frequency energy, a form of non-ionizing radiation, is emitted by cell phones.
The only biological consequence that can be definitively proven to have occurred as a result of exposure to radio frequency energy is tissue heating, according to the existing scientific data.
According to public health research, there is no link between using a cell phone and being exposed to radio frequency energy that can cause health issues.
