Anytime something plugs in or operates with a battery there is EMF radiation.
Iphones and wireless computers are always searching for a wireless signal,
so even if just playing games,
they are constantly putting out a wi-fi signal.
the iphone is always putting out radiation when it`s turned on.
here`s the real problem though,
every thing around you is putting out radiation,
cell phones (including other people`s phones)
and on and on.
So even though you can use a meter to measure specific areas,
it doesn`t even begin to show you the cumulative radiation you get just by living in our world today.
I have found a two level approach that helps me feel more focused and energized,
I wear a Bioelectricshield to protect from everything around me,
AND put a WaveShield on my phone to add additional protection.
We may not know all the answers yet about how harmful this radiation is,
so the more we can do to protect ourselves,
the better off we`re going to be.
