factor in how much exposure a person receives. Those persons 

who spend long periods of time on their hand held mobile 

phones could consider holding lengthy conversations on 

conventional phones and reserving the hand held models for 

shorter conversations or for situations when other types of 

phones are not available.

People who must conduct extended conversations in their cars 

every day could switch to a type of mobile phone that places 

more distance between their bodies and the source of the RF, 

since the exposure 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

  a headset with a remote antenna to a mobile phone carried 

at the waist 

Again, the scientific data do not demonstrate that mobile 

phones are harmful. But if people are concerned about the radio 

frequency energy from these products, taking the simple 

precautions outlined above can reduce any possible risk.
