Comparative study of radiofrequencies field levels of base stations

This work has established the electromagnetic fields from the base stations under investigation were beyond background levels. The highest SAR value of 1.17 Wkg^(-1) was obtained by GLO which is less than the International Commission on Non-ionizing Radiation Protection (ICNIRP, 2003) localized safety limit of 2 Wkg^(-1) for the human head, while MTN gave the lowest SAR value of 0.18 Wkg^(-1) which is also far below the reference dose limits. Considering the nine (9) base stations under investigation, MTN base station registered the lowest value of SAR. Thus, GSM base stations users are exposed to different electric & magnetic field levels but such levels are within such limits set by the International Commission on Non-ionizing Radiation Protection (ICNIRP).
