"I try not to exceed a half hour or an hour a day," Seger says of his cellphone use. "Everything is a matter of dosage." He suggests keeping cellphones at least 12 inches from the body and using the speakerphone.

Woollams uses his cell sparingly and puts it on speakerphone. His older kids -- aged 14, 23 and 26 -- "are encouraged to only text at most. I don't want them to carry the phone on their bodies when they are on."

Repacholi owns two cellphones and says he has no concerns about using them. For those who do, he recommends using a hands-free kit, which can reduce exposure levels by a factor of between 10 and 100.

Boice makes approximately five cellphone calls a day. He uses a wired earpiece -- not for fear of EMFs but because "I'm getting older and don't hear so well anymore," he says.
Aberg removes her phone's battery when she visits patients. She advises against wireless phones and wireless computer connections at home because, she says, "you are exposed to EMFs all day and all night."

Cardis is not a heavy talker ("I have little time!") but says, "If consumers are worried about a possible risk, the use of hands-free kits or earpieces is a very good way to reduce exposure."

Kundi dials on a landline whenever available and suggests not using cellphones where reception is weak, because they boost their signal to maintain connectivity, thus increasing EMF exposure.single page
