Measurement and Evaluation of Radiation Power Density Emitted from Mobile Cellular Base Stations in Abuja and its Environ, Nigeria

Abstract

This paper presents measurement and evaluation of radiation power density emitted from mobile cellular base stations in Abuja and it’s environ. Forty (40) mobile base stations with ten (10) each from AIRTEL, ETISALAT, GLO and MTN located in areas with high population were randomly examined across Abuja. Broadband analysis method was employed in the measurement of the radiation power density. The results obtained shows that most of the base stations recorded lower radiation power density below the safety standard value of 4.5watt/m2 , 22.5 watt/m2 for 900MHz frequency though few base stations recorded above standard value: GLO-BS02, GLO-BS03 and MTN-BS02 recorded 59.02 mW/m2, 39.76 mW/m2 and 46.70 mW/m2 respectively. The result also revealed that as distance increases, the mean power density reduces. This is to said that human exposure to radio frequency radiation have less or no health hazard at distance far away from the mobile cellular base station.

Prediction of electromagnetic power density emitted from GSM base stations by using multiple linear regression

“…According to the results obtained, 59.02 mW/m2, 39.76 mW/m2 and 46.70 mW/m2 values were measured, respectively. The result revealed that the average power density decreases as the distance increases [28]. In another study on the brain, researchers concluded that EMR may play a role in the neurotransmitter disorder of the brain [29].…”

Discovering the spatial locations of the radio frequency radiations effects around mobile towers

“…Direct exposure to high levels of electromagnetic radiation leads to increase the temperature of the human body, which leads to damage the body tissues in case of disability to dissipate the excess heat well [23]. The non-thermal effects are classified as more harmful effects on humans than the thermal effects because they cause memory problems, sleep disturbance and headache [23], [25]- [27]. Tissues exposed to radiofrequency radiation absorb quantities of strand measured per unit mass, which is moreover known as the SAR, exposure guidelines are defined by the power density as they represent the physical values for determining those guidelines [26].…”
