Radio wave exposure and Specific Absorption Rate (SAR) information.
Nowadays mobile telephone manufacturers have taken the SAR issue into their design consideration. The SAR requirements are based on scientific guidelines that include safety of all persons, regardless of age and health.
The radio wave exposure guidelines employ a unit of measurement know as the Specific Absorption Rate or SAR. Tests for SAR are conducted using standardized methods with the phone transmitting at its highest certified power level in all used frequency bands.
While there may be differences between the SAR levels of various phone models, they are all designed to meet the relevant guidelines for exposure to radio waves.
SAR data information for residents in countries that have adopted the SAR limit recommended by International Commission of Non-Ionizing Radiation Protection (ICNIRP), which is 2 W/kg averaged over ten (10) gram of tissue (for example European Union, Japan, Brazil and New Zealand).
Some mobile phone models available in Singapore do meet the above-mentioned standard at around 1.5 W/kg (10g).
