Electromagnetic radiation consists of waves of electric and magnetic energy moving together (i.e., radiating) through space at the speed of light. Taken together, all forms of electromagnetic energy are referred to as the electromagnetic "spectrum". By the way, in Yemen nobody asks or interested about public health concerned Radio Frequency Radiation (RFR) (invisible pollution) emitted from mobile base stations even government presented by the Ministry of Telecommunication and Information Technology. We can't imagine that this related ministry doesn't have any radio frequency measurement equipment. WHO branch Yemen, Sana'a doesn't interested too for evaluating health risk accused by RFR. Mobile phone sector in Yemen increased dramatically during last ten years where you can see everywhere in Yemen randomly Base Transmitted Stations (BTS) antennas. The aim of this paper is to measure and study the intensity of Electromagnetic Radiation (EMR) known as the power density (W/m2) emitted from mobile phone base stations operated by four mobile networks in Sana'a Yemen. The power density of spot measurement at different distances of transmitted antennas of base stations are measured. Several measurements were done at schools, hospitals, universities, and main squares in Sana'a. We obtained several results that we compared it with international standards.
