INVESTIGATING ELECTROMAGNETIC FIELD CONCENTRATION IN OUR ENVIRONMENT

ABSTRACT

This study aimed to identify sources of electromagnetic fields (EMF) in the Oshimili South Local Government Area of Delta State, measure the magnitude of electromagnetic radiation from these sources, and simulate EMF radiations using MATLAB. Employing a descriptive and correlational research design, the study utilized direct observations, extensive fieldwork, and direct measurements to identify and categorize sources of EMF. Electromagnetic field meters and antennas were employed for accurate data collection. The study employed MATLAB for the simulation of EMF radiations. Data analysis involved descriptive statistics, hypothesis testing using t-tests or ANOVA, and a comprehensive categorization of EMF sources. The study identified sources with higher electromagnetic field strength, such as High Voltage Transmission Lines, Transformers, Satellite Communication Systems, Cellular Towers, and Broadcast Towers. Items with lower electromagnetic field strength included Laptop Computers, TV Sets (CRT/LED/LCD), Refrigerators, and WiFi Networks. A three-dimensional plot visualized EMF signals. ANOVA results indicated significant differences among EMF signals recorded in the home and outdoors. Recommendations include minimizing high EMF exposure and government implementation of reduction efforts. Limitations include potential variations in natural EMF sources, while future studies could explore longitudinal analyses and population-specific investigations.
