The antennas contained in , including , emit radiofrequency (RF) radiation ( such as ); the parts of the head or body nearest to the antenna can absorb this energy and convert it to heat or to synchronised (the term 'heat', properly applies only to disordered molecular motion). Since at least the 1990s, scienti.
