Specific Absorption Rate (SAR) is the amount of radio
frequency (RF) radiation absorbed by us when we use a mobile phone. Every phone
or handset is measured and rated in terms of their SAR. It is common in U.S.A
and Canada. The maximum allowable SAR for any handset is 1.6 watts per
kilogram. So while buying any cell phone do check its SAR ratings.
We are not sure whether these radiations are harmful to
users or not, some studies show that these radiations are harmful and linked
them to infertility,
