France,^[76]

Germany,^[77]
<http://en.wikipedia.org/wiki/Mobile_phone_radiation_and_health#cite_note-76>
and Sweden^[78]
<http://en.wikipedia.org/wiki/Mobile_phone_radiation_and_health#cite_note-77>
have recommended measures to minimize exposure to their citizens.
Examples of the recommendations are:
* Use hands-free to decrease the radiation to the head.
* Keep the mobile phone away from the body.
* Do not use telephone in a car without an external antenna.
The use of "hands-free" was not recommended by the British Consumers'
Association in a statement in November 2000 as they believed that
exposure was increased.^[79]

However, measurements for the (then) UK Department of Trade and
Industry^[80]

and others for the French l'Agence française de sécurité sanitaire
environnementale^[81]
<http://en.wikipedia.org/wiki/Mobile_phone_radiation_and_health#cite_note-80>
showed substantial reductions. In 2005 Professor Lawrie Challis and
others said clipping a ferrite bead
<http://en.wikipedia.org/wiki/Ferrite_bead> onto hands-free kits stops
the radio waves travelling up the wire and into the head.^[82]
