Scientific opinions vary regarding risks associated with radiofrequency (RF) radiation exposure from cell phone use. While some studies have shown a correlation between the occurrence of certain adverse health effects and long-term use, a definitive cause and effect relationship has not been established.

The Federal Communications Commission (FCC) has adopted exposure limits to RF energy with which all cell phones legally sold in the United States must comply.  These limits are expressed in Specific Absorption Rate (SAR), which is a measure of the amount of RF energy absorbed by the body while using a mobile phone.
