level drops off dramatically with distance. For example, they could
switch to:
• a mobile phone in which the antenna is located outside the
vehicle,
• a hand-held phone with a built-in antenna connected to a
different antenna mounted on the outside of the car or built into
a separate package, or
• a headset with a remote antenna to a mobile phone carried at
the waist.
Again, the scientific data does not
demonstrate that mobile phones
are harmful. But if people are concerned about the radiofrequency
energy from these products, taking the simple precautions outlined
above can reduce any possible risk.
