Is a mobile with a lower SAR value safer than one with a higher value?
If the SAR values are lower than the basic restriction (2 W/kg for localised exposure at the head and upper body level), then both mobiles will be considered safe. In fact, the SAR value given in the mobile’s documentation is a maximum value, which is only ever reached when commencing a call or under special circumstances. This happens when you’re at the edge of the coverage area and the signal received from the station is weak or when the speed of movement is very high and many transfers between cells take place. Otherwise, exposure is lower.
