Abstract

Electromagnetic intensity investigation of emitted non-ionizing radiation from base transcriptive stations in the urban region of southern Iran Abbasi F, Badeenezhad A, Abouee E, Shademanpour Z, Janghorban F, Janatshoar H, Naserpour M, Mohammadpour A. Electromagnetic intensity investigation of emitted non-ionizing radiation from base transcriptive stations in the urban region of southern Iran. Int J Environ Health Res. 2024 Dec 2:1-12. doi: 10.1080/09603123.2024.2435484. Epub ahead of print. PMID: 39620927. Abstract Their monitoring in urban regions is essential for policymakers and the population. In this study, the electromagnetic intensity (EMI) was measured around 30 stations of base transcriptive stations (BTS) at both distances lower than 20m and higher than 200m using real-time equipment SMP2-dual in summer and winter. Results have shown that EMI in summer (range: 2-6500 mW/m2) was more than in winter (1.5-5000), and the intensity of about 93% of samples exceeded WHO standards. EMI has consistently decreased with the increasing distance from BTS. There was a negative correlation between the temperature and EMI in summer and humidity and EMI for both distances. The mapping of EMI depicted the highest value of EMI across the central region from south to eastern north at a distance lower than 20 m in winter. The clustering of the EMI in this region was influenced by the geographical location of BTS. pubmed.ncbi.nlm.nih.gov

Main findings

EMI measured around 30 BTS ranged from 2–6500 mW/m2 in summer and 1.5–5000 mW/m2 in winter, with higher values in summer. The abstract reports that about 93% of samples exceeded WHO standards and that EMI decreased with increasing distance from BTS. Negative correlations were reported between temperature and EMI in summer and between humidity and EMI for both distances; mapping/clustering suggested highest EMI in a central region influenced by BTS geographic location.
