Abstract

Background and Objectives: Although technological advancements and use of electronic devices promote the general welfare, they are associated with many biological risks. Given the public concern about the possible health effects of base transceiver station (BTS) antennas’ waves and the presence of these antennas in urban areas and near residential areas, it is necessary to identify these sources and their possible effects. So the aim of this study is to evaluate intensity of microwave radiation of Hamraheaval BTS antennas and its effect on the general health of residents around the antennas in the city of Qazvin 2016-17. Materials and Methods: In this descriptive-analytical study, fourteen 1800MHz- macrocell BTS antennas of Hamrah-e-Aval operator were identified in 3 urban districts of Qazvin and measurements were later made in one of the sectors of each fourteen BTS antennas in the near (Horizental distances 0, 10 and 20 m) and far away fields (Horizental distances 100 and 300 m) at the front door of the houses. At the same time, efforts were made to evaluate the health status of 231 residents of the same points of measurement. Questionnaires data were collected and then analyzed using Pearson's correlation coefficient, one-way ANOVA, and independent t-test in SPSS software ver. 23. Results: In the present study, the highest mean electromagnetic energy density was 85% of the standard public exposure (National Standard 8567). The results of one-way ANOVA revealed no significant difference between the groups in terms of the distance and electromagnetic energy density. The results showed that the majority of residents (51.9%) were in a good health status. According to the results of one-way ANOVA, there was a significant difference between the electromagnetic energy density with urban districts 1, 2 and 3, and the lowest average electromagnetic energy density at different distances was observed in district 3 where density and height of buildings were higher. Disscusion & Conclusion: The present research showed that all measurements on BTS antennas’ waves at all studied distances were below the permissible limit. The results also showed that the BTS antennas had no harmful effects on the health status of the residents living around these antennas. Finally, the results revealed that tall buildings locating around the BTS antennas can be considered as the main barrier of these waves.
