Such discrepancies result from automatic changes in device power
necessary to ensure that the device operates at a minimum power
level required to be connected with network.
Although SAR values might vary for different models of phones or
even for different positions of the same model, they are all
compliant with regulations pertaining to safe level of radiation.
According to WHO current research, there is no need to apply any
special restrictions in using portable devices. According to WHO,
in order to reduce radiation, a length of conversation should be
reduced, or headset or speakerphone should be used, or the
phone should not be held in proximity to head or body.
SAR values might also vary due to various reporting and testing
requirements in different countries as well as to frequencies in a
given network.
