Since sticking your hp to your head causes harm due to the radiation, does it help if you use ear piece?
Radio Frequency (RF) exposure and SAR
Your mobile phone is a low-power radio transmitter and receiver. When it is turned on, it emits low levels of radio frequency energy (also known as radio waves or radio frequency fields).
Governments around the world have adopted comprehensive internation saety guidelines, developed by scientific organizaions, e.g ICNIRP (International Commission on Non-Ionizing Radiation Protection) and IEEE (The Instituite of Electrical and Electronics Engineers Inc.), through pperiodic and thorough evaluation of scientific studies. These guidelines establish permitted levels of radio wave exposure for the general population. The levels include a safety margin designed to assure the safety of all persons, regardless of age and health, and to account for any variations in measurements. Specific Absorption Rate (SAR) is the unit of measurement fot the amount of radio frequency eneergy absorded by the body when using a mbile phone. The SAR value is determined at the highest certified power level in laboratory conditions, but the actual SAR level of the mobile phone while operating can be well below this value. This is beccause the mobile phone is designed to use minimum power required to reach the network.
Variations in SAR below the radio frequency exposure guidelines do not mean that there are variations in safety. WHile there may be differences in SAR levels among mobile phones. Before a phone model is available for sale to the public, it must be tested and certified to the FCC that is does not exceed the limit established by the Government-adopted requirement for safe exposure. The tests are performed in positions and locations (that is, at the ear and worn on the body) as required by the FCC for each model. For body worn operation, the phone has been tested and should meet FCC RF exposure guidelines when the handset is positioned a minimum of 15 mm from the body without any metal parts in the vicinity of the phone or when used with the original body worn accessory intended for the phhone. Use of other accessories may not ensure compliance with FCC RF exposure guidelines.
...dun anyone from Africa read their mobile phone user manual?
