Mobile measurement of radiofrequency electromagnetic field exposure level and statistical analysis

• We measured radiofrequency electromagnetic field exposure level as mobile.
• Measurement values are not in normal distribution.
• Variances between independent variables are not homogeneous.
• According to Spearman’s rho correlation coefficient, there is no strong correlation.
• All measurement values are below the reference levels of ICNIRP.

In this study, radiofrequency electromagnetic field exposure levels were measured as mobile on the main streets of Diyarbakır during a week. The measurements were carried out using high precision spectrum analyzer with an isotropic antenna mounted on the top of a car. With this mobile measurement, large areas were measured in a short time and information about characteristics of electromagnetic environment was obtained quickly. Measurement results showed that measurement values were not in normal distribution and variances between independent variables were not homogeneous. According to Spearman’s rho correlation coefficient, there was no strong correlation between measurement days. In terms of mean electric field values, contribution of each band to total band was arranged as UMTS DL, GSM900 DL, GSM1800 DL, TV4-5, FM, and TV3 band, respectively. It was determined that all measurement values were below the reference levels of the International Commission on Non-Ionizing Radiation Protection.
