To the Editor: Dr Volkow and colleagues reported on the correlation between glucose metabolism in the brain and the presence of active cell phones placed near the heads of participants.1 We believe this study is flawed, as there is no mechanism other than heating by which the radiofrequency fields from a cell phone could affect human tissue. The highest temperature elevations that occur in the brain during cell phone use as a result of the radiofrequency fields from the cell phone are on the order of 0.1°C to 0.2°C,2 temperature elevations that are smaller than those resulting from physical activity. The photon energy from the cell phone is too small to break even the weakest bonds, and the frequency of the fields is too high to affect ion transport.3
