Radio Frequency EMF Exposure due to Gsm Mobile Phones Base Stations: Measurements and Analysis in Nigerian Environment
Abstract
For some time now, members of the public have been concerned about the possible feared health impacts and safety of new RF technologies, including radar, radio and television broadcasting facilities, microwave ovens, point-to-point microwave radio, and satellite communications systems. The most recent concern is the safety of mobile phones and their base stations (BSs). In Nigerian some people believed that exposure to radiation from BSs for long period could cause different diseases like cancer, destroys reproductive organs, congenital anomalies, epilepsy and persistent headache and some of the BSs were installed near the home of residence. Owing to the growing concern, this study was conducted to evaluate the radio frequency radiation levels near several mobile phone BSs in GRA, Benin City, Nigeria. Measurements in terms of power density were made to check the exposure level at public locations. The data (power density) were collected from three (3) major GSMoperators BSs in Nigeria; all the BSs were located in GRA, Benin City, Nigeria. For each of these BSs the measurements were taken at 5m intervals to 100m from the BSs. From the results, the maximum of power density obtained for GLo, MTN and Airtel are 1.62mW/m2, 3.04mW/m2 and 1.52mW/m2 respectively. These values are quite small compared to international standard limits like those adopted by the International Commission on Non-ionizing Radiation Protection (ICNIRP) which is 9mW/m2 for the public and 22.5mW/m2 for those professionals involved in telecommunication industry.
