Concern about human exposure to radiofrequency (RF) is not new. The conveniences and satisfaction derived in the use of GSM mobile phone is being threatened by claims of adverse effects on human health by radiation coming from this device. This radiation belongs to the type called non-ionizing radiation the health hazard of which remains debatable. Research has not been carried out on possible ...

THE MAJORITY OF THE RADIOFREQUENCY ENERGY emitted by a cellular telephone is absorbed by the hand and head of the user. The total energy absorbed is a function of the specific absorption rate, duration of use, and the manner in which the phone is used. In addition to concerns about potential harmful effects of such exposure, such as the issue of risk of brain cancer, change in brain function re...

Mobile phones are two-way radios that emit electromagnetic radiation in microwave range. As the number of mobile phone users has reached 6 billion, the bioeffects of exposure to mobile phone radiation and mobile phone electromagnetic interference with electronic equipment have received more attention, globally. As self-monitoring of blood glucose can be a beneficial part of diabetes control, ho...
