Through various studies,
it has been proved that excessive usage of mobile phone causes negative impact
on health and when signal bars of mobile phones are comparatively less in number , these devices create much more negative radiations than usual.
Mobile phone towers are as harmful as mobile phones. German surveys prove that
residents within the range of 400 meters from mobile towers are three times
more likely to suffer from carcinogenic effects in the span of 10 years. The
people living on the upper storey in such buildings have much increased chances
of getting brain tumors.
