EM exposure in the range of non up to 3GHz is mainly sourced from mobile phone base stations, broadcast towers and radar facilities. This reviews based on previous researcher obtained results and methods in order to determine the best technique to measure the exposure. levels by considering the specification of the antennas installed and area of the base stations itself was also reviewed. It was found that numerous study of NIR exposure level has been conducted in other countries, whi the studies used field meter to were far lower than the limit recommended by EM exposure in the range of non-ionizing radiations (NIR) which falls in the radio up to 3GHz is mainly sourced from mobile phone base stations, broadcast towers and radar facilities. This reviews based on previous researcher obtained results and methods in order to nique to measure the exposure. Moreover, the estimation of exposure levels by considering the specification of the antennas installed and area of the base stations also reviewed. It was found that numerous study of NIR exposure level has been conducted in other countries, while Malaysia has become aware of the importance eter to carry out the measurement, and the exposure level obtained were far lower than the limit recommended by World Health Organization (WHO).agnetic exposure level; base station; electric field strength; geographical
