Specific Absorption Rate (SAR) – actual absorption.
As recommended by ICNIRP, the border value of
SAR for portable equipment is 2,0 watts per
kilogram (W/kg).
SAR value is determined at the maximum transmit
power; the actual SAR value while the device is
working is usually lower than the indicated level.
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 the network.
Although SAR values might vary for different models
of phones or even for different positions of use - 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 mobile
devices. According to WHO, in order to reduce
radiation, a length of conversation should be
reduced, or headphones or speakerphone should be
used, not be hold the phone in proximity to head or
body.
