This study presents an assessment of non-ionizing radio frequency (RF) radiation emitted by mobile phone base stations transceiver (BTSs) in the city of Al-Ajailat, Libya. Using the HF32D broadband electromagnetic field analyzer, measurements were conducted at 40 outdoor locations near four different towers, covering the frequency range of 800 MHz to 2.7 GHz. Additional readings were taken vertically across seven floors of a building adjacent to one of the towers. Measurements were performed hourly over a 13-hour period to capture temporal variations. Results were analyzed with respect to ICNIRP exposure guidelines and international benchmarks. The findings indicate that the measured power density levels were well below the ICNIRP reference limits. While the study confirms compliance with international safety standards, it highlights variations in exposure based on distance, elevation, and time of day. These insights may help inform public safety planning and future studies of RF exposure in urban environments. .....................
