On parle ici du 680. Ceux qui emettent de fortes radiations sont les 600 et 650

'We should all support Palm for reducing radiation on their Treo line of smartphones. Previous models have VERY HIGH SAR radiation. You may not care about that now but in ten years you might change your mind. The Treo 680 has very low radiation, comparable with the lowest in the market. Aside from that the phone is great. Stylish and well designed. It is sometimes confusing to navigate but with the help of the user guide I'm learning.'
