The solution? Use the phones as little as possible and use a headset so as to remove the source of electromagnetic radiation from (the phone) as far from your head as possible. Perhaps wear the phone in a carrier with its inside having a metal plate to protect the part of your body near the phone. Remember that a little distance equals a lot of protection because the phones emit at a very low power in the first place and the strength of the e/m field is INVERSELY proportional to the SQUARE of the distance from the source.
