Abstract: “Although the important role of the immune system in defending the human body against infections and cancer, only few studies on the possible effects of radio frequency radiation on the function of human immune cells have been undertaken. The present study was performed to investigate whether radio frequency (RF) field exposure could affect the activity of human immune system cells by studying the activity and behavior of human leukocytes (white blood cells) upon exposure to radiofrequency fields. Human blood Leukocytes were exposed to different temperatures and 1800 MHz RF radiation (SAR of 1.25 W/Kg, Power density of 0.1 mW/cm2) from a mobile phone when placed within a distance of 5 cm from the microscope stage. Our results indicated that when 1800 MHz RF field was applied, the speed increased above the value observed at the same temperature, and the maximum speed exceeded that measured value at any temperature by approximately 50%. The average time for the leukocytes to respond to th”
