Seasonal Monitoring Electromagnetic Situation in the Radio-Frequency Range of Mobile Communication

Abstract

Introduction. The study of the electromagnetic environment created by mobile communication terminals (MCT) is one of the important tasks of modern preventive medicine. In the study, the assessment of the electromagnetic environment created by MCT according to fluence values. Material and methods. The fluence level of MCT radiation was determined in the territory of the Crimea using a mobile monitoring system. The number of paired (seasonally) fluence measurement points accounted for 2102. At each point, the level of electromagnetic radiation (EMR) was determined sequentially from two identical MP (Samsung G3) in voice mode with the remote subscriber. Results. The average fluence value in Crimea for the year amounted to 1.45 ± 0.06 μW/cm2. In the winter (non-resort) season fluence accounted for 1.34 ± 0.05 µW/cm2, in the summer (resort) season -1.54 ± 0.05 µW/cm2. A comparative non-parametric analysis of the winter and summer fluence values in the resort regions revealed significant differences, whereas in non-resort regions there were no significant differences. Obtained as a result of monitoring of the electromagnetic situation, the data showed significant heterogeneity of fluence by administrative units within the Republic of Crimea from 0.92 ± 0.03 in the Belogorskiy to 2.11 ± 0.07 μW/cm2 in the Chernomorsky regions, which indicates the difference in mobile coverage areas in Crimea. Significant differences between the fluence values obtained in the winter and summer seasons for resort regions can be explained by the uneven workload of base stations due to the seasonal dynamics of the influx of tourists. Conclusion. As a result of the work done, an average annual fluence value of 1.45 ± 0.06 µW/cm2 was obtained, its considerable heterogeneity and reliable seasonal changes were revealed.
