So how safe are mobile phones?

                So how safe are mobile phones?

There is concern at the moment over the use of cellular phones and their possible health implications. All the research is inconclusive so the bottom line is, cellular phones may be a potential health hazard.
Different cell-phone models emit different amounts of radiation, so one way to reduce your exposure is to purchase a cell phone with a lower SAR (specific absorption rate), a number that indicates how much radiation is absorbed by the human body when the handset is being used at maximum power.
The FCC requires cell phone manufacturers to ensure that their phones comply with these objective limits for safe exposure. Any cell phone at or below these SAR levels (that is, any phone legally sold in India) is a "safe" phone, as measured by these standards. The FCC limit for public exposure from cellular telephones is an SAR level of 1.6 watts per kilogram (1.6 W/kg).
