These limits arepart of comprehensive guidelines and establishpermitted levels of RF energy for the generalpopulation. The guidelines were developed byindependent scientific organisations through periodicand through evaluation of scientific studies. Thelimits include a substantial safety margin designed toensure the safety of all persons, regardless of ageand health.The exposure standard for mobile phones employs aunit of measurement known as SAR(the SpecificAbsorption Rate). The SAR limit recommended by theEU Council is 2.0W/kg *.* The SAR limit for mobile phones used by the public is 2.0 watts/kilogram (W/kg) averagedover ten gram of body tissue. The limit incorporates a substantial margin of safety to giveadditional protection for the public and to account for any variations in measurements. The SARvalues may vary depending on the national reporting requirements and the network band.
