" This study focuses on the effect of electromagnetic radiation (EMR) emitted by cell phone towers on human tympanic temperature (T), blood oxygen saturation (SPO2%), heart pulse rate (HPR), systolic blood pressure (SBP) and diastolic blood pressure (DBP).
The sample is 136 employees of both genders (56 female, 80 male), with mean age 40 Yrs., and the mean duration of employment 14 Yrs., were randomly chosen as a sample to reach the desired objective. This sample was taken from Nablus and Jenin municipalities, which are 70 m and 50 m from cell phone towers, respectively.
The mean values of the measured power flux density were 52.58 µW/m2 and 31.76 µW/m2 in Nablus and Jenin municipalities, respectively. The electric field and the magnetic field values were calculated from the measured power flux density, which were less than the standard levels for exposure to EMR of cell phone towers. The measurements of tympanic temperature, blood oxygen saturation, heart pulse rate and arterial blood pressure (systolic and diastolic) of the selected employees were measured before and after exposure to signals of cell phone towers. This study shows that the health effects of signals of cell phone towers depend on the power flux density.
The statistical results showed that Pearson correlation coefficient (R) between power flux density and the dependent variables are varying from 0.294 to 0.657, and the probabilities (P) are < 0.05 for all health factors."
