This study concerns about the effects of Electromagnetic radiation from antennas on arterial blood pressure (systolic (SBP), diastolic (DBP)), heart pulse rate (HR), blood oxygen saturation (SPO2%) ofchildrenÂs schools. The sample consists of 273 students of both genders (91 female, 182 male), classified into two groups; 10-12 years and 13-16 years. The sample was taken fromthree different schools inNablus area. Themeasured power flux density in the first school was 1.862mw/m2 and 353.166µw/m2 in the second school and 18.278µw/m2 in the third one. Measurements of blood oxygen saturation, heart pulse rate, arterial blood pressure (systolic and diastolic) were taken for the selected sample before and an after exposure to Electromagnetic radiation from antennas. Positive correlation (Pearson Correlation Coefficient) was found for all measured variables. The statistical results showed that Pearson correlation coefficient (R) between the dependent variables (SBP, DBP, HR, SPO2%) before and after the exposure to electromagnetic radiations from antennas is strong and the Probability (P) is < 0.05. This study shows that there is a significant shift of the measured mean values of arterial blood pressure (systolic and diastolic), heart pulse rate, and blood oxygen saturation of the children due to exposure of electromagnetic radiation from antennas.
