[Effects on function of human lymphocytes exposed to electromagnetic fields with a frequency from 1,500 to 2,000 MHz].

Normal human peripheral blood lymphocytes were irradiated for 10 or 5 min with frequencies from 1.5 to 2.0 GHz. The frequency of 1.8 GHz overlaps that of mobile phones and leads to a significant reduction of the T-cell mediated antibacterial activity.
