Cell Phone Radiation
[Note the heating effect on the frontal lobe]

Cellular phones or mobile phones are used today for long periods of time, often with people unaware of the degree and impact mobile phone radiation has. Reports from various sources achieve different conclusions about damage to human health; some stating that no conclusive evidence is available while others establish a direct correlation between brain tumors and health conditions to extended exposure to mobile phone radiation. However, these are the facts about cellular phone radiation.
Cellular phones use radiowaves, wavelengths on the longer end of the electromagnetic spectrum, in the band of about 800 to 900 MHz (megahertz, [frequency]). Unfortunately, the human body is known to absorb the output radiation produced by cell phones in a measurement known as the Specific Absorption Rate (SAR). The SAR measures the amount of energy absorbed by the body from handset radiation. The energy absorbed by the body decreases with increases in distance as radiation is dissipated into the environment. The United States government regulates the maximum legal SAR for a handset to be 1.6 watts per kilogram. In the European Union, the maximum SAR is 2.0 watts per kilogram. The Unites States government measurement of SAR involves only testing the absorption of energy from talking on the phone and does not compensate the SAR for other radios waves from such sources as wifi, bluetooth, etc. These add to increased energy output in from the radiowaves. In addition, smart phones in particular produce increased amounts of radiation due to their internal components.
Data exists that directly proves that exposure to radiation causes harm to cells, especially over long periods of time, in greater doses. Mutations, cancer, and even brain tumors have been a result of exposure to radiation with a more adverse or a quicker effect occurring at greater amounts of exposure.
It is important to remember that modern day phones generally produce less radiation than those of the late 1980s and that steps are being taken to attempt to lessen hazards associated with cellular communication.
