Electromagnetic radiations, emitted from cellular phone, modify cutaneous blood flow

Aim. To verify wheteher the non-ionizing electromagnetic radiations (REMs) (frequency: 3x108Hz-3x1011Hz), emitted from cellular phone (CF), could influence the cutaneous blood flow in healthy volunteers. Materials and methods. Thirty healthy volunteers (14 M and 16 F; age: 18-53) were enrolled into the study. Measurements, under standard conditions (temperature and humidity), were performed using Laser-Doppler He-Ne flowmetry. Continuous survey was made possibleby an optical fibre probe applied on the cutaneous area of the ear. Microflow values were recorded witnout CF contact (T0); with CF turned off (T1); with CF turned on (T2); with CF turned on and in reception (T3). Results. In comparison with basal microflow (BM) in T0, that was 51.26 P.U., the results put in evidence a noteworthy rise in the cutaneous blood flow. In fact, in T1 was observed a mean microflow (MM) of 83.62 P.U. (rise of 61.38% in comparison with BM); in the T2 was observed a MM of 118.79 P.U. (rise of 131.74% in comparison with BM); in the T3 was observed a MM of 132.08 P.U. (rise of 157.67% in comparison with BM). Conclusions. The non-ionizing REMs, emitted from CF, induce a significant modification of the normal cutaneous microcirculation. This modification doesn’t derive from the variation of the temperature induced by the simple contact with the CF.
