Abstract

Measurement of electric field strength, magnetic field strength and power density were carried out using two instruments, electro smog meter (model TES -92) and ELF detection meter (model 480823) at an interval of 2 m starting from the base of the source. The maximum electric field strength, magnetic field strength and power density obtained in this research are 5.09 V/m, 0.2037 A/m and 0.5002 W/m2 respectively. Three of 132 KVA are located at three different communities, Ayede/Jericho, IITA and Ojoo, and three of 11 KVA are also located at three different communities, Odo – Ona, State secretariat and Sango- UI. The maximum electric field strength, magnetic field strength and power density measured as radiated from 132 KVA are 5.09 V/m, 0.0135 A/m and 0.500 W/m2 (Ayede/Jericho), 3.535 V/m, 0.003694 A/m and 0.06874 W/m2 (IITA), 1.3284V/m, 0.00942 A/m and 0.00457 W/m2 (Ojoo) respectively. Also, the maximum electric field strength, magnetic field strength and power density measured as radiated from 11 KVA are 0.0658 V/m, 0.02037 A/m and 0.0006278 (Odo- Ona), 1.619 V/m, 0.00393 A/m and 0.0696 W/m2 (State secretariat), 0.6046 V/m, 0.00225 A/m and 0.00155 W/m2 respectively. These results constitute 0% of the recommended values by the ICNRP. Therefore, peoples living or carrying out other activities along power lines at these sites will not suffer any health hazards due to electromagnetic radiations emanating from the power lines.
