Measurement of Electric Field Radiation from 11KVA High Tension Power Line and Its Environmental Effects in Calabar Metropolis, Nigeria

摘要

This study measured the electric field from high tension 11 KVA power line by varying the distance between 5 m to 30 m respectively using electrosmog meter. The results revealed that the highest amount of radiations of 1.601 V/m, 1.568 V/m, 1.451 V/m, 1.345 V/m, 1.238 V/m, 0.996 V/m and 0.579 V/m respectively were observed at a distance of 5 m in all the locations. In all cases, the measured radiations were very far below the exposure limits set by International Commission on Non-Ionizing Radiation Protection. It is therefore recommended that one should not stay very close to high tension power line even though short term exposure may not produce immediate health effect. Nevertheless, staying close to the source of radiation, strength of the electric field generated and long term exposure can be dangerous to individual health.
