Therefore, this study was conducted to measure the levels of electromagnetic radiation emitted from the antennas of cellular base stations in Gaza governorate as well as to evaluate the citizen’s awareness and practices regarding potential health risks and mitigation methods of exposure to electromagnetic radiation emitted from cellular base stations, respectively. Fifty cellular base stations out of 197 stations were selected depending on the criteria of selecting one site per kilometer using Global Positioning System (GPS). Electromagnetic power density, electric field strength, and the magnetic field strength emitted from cellular base stations were measured using Narda-550. Assessment tool for observation was used to collect operational information of each station. A structured questionnaire with four-level Likert rating scale was used to survey 384 mobile phone users from the areas surrounding the selected cellular base stations. The results showed that the electromagnetic radiation levels of all stations were low and less than the national and international acceptable limits. Furthermore, the awareness of participant about health risks that could result from exposure to electromagnetic radiation emitted from cellular base stations and mobile phones was low. Nevertheless, the participant’s practices in mitigating the adverse impacts of electromagnetic radiation emitted from cellular base stations and mobile phones on their health were good.展开更多

The 12 measuring points are chosen on the roof, inside and outside of the building, which has a 5G base station on the top. The electric field intensity, magnetic field intensity, and power density have been measured. The measurement methods include background measurement and work measurement. Background measurement is the measurement of environmental electromagnetic field (EMF) before the installation of 5G base station while the working measurement is the measurement after the installation of 5G base station. The evaluation methods include t-test for qualitative evaluation and electromagnetic gain for quantitative evaluation. The results show that the electromagnetic environment after the installation of 5G base station in most places is different from that in the background. And the environmental electromagnetic fields in certain parts are lower than those in the background. The conclusions are as follows: 1) The electromagnetic environment of 5G base station is far lower than the control limit of the national standard and conforms to the national standard;2) The electromagnetic environment of 5G base station has little impact on the electromagnetic environment;3) It is not sufficient to assume that 5G is harmful to health without the results of the epidemiological investigation;4) Before the construction of 5G base station, do background EMF detection, which can provide support for future evaluation.展开更多
