SAR is the amount of radio frequency energy absorbed by the
body when using a mobile phone. India has adopted a stringent SAR limit of 1.6
watts per kg. Also directions have been given to prominently display the SAR
value on every handset.
The risks of long-term exposure to radio frequency waves have
been established in a recent study. Younger children should be discouraged from
using cellular phones, because their skulls are thinner than adults and cells
are more likely to be sensitive to mobile-phone radiation.
