Nigeria had maintained substantial intensification in the perspective of the mobile communication utilization, services improvement and sustainable broadband regime and this development is presumed to persist into the conceivable future with the evolution of the contemporary 6G, 5G, 4G and 3G mobile communication technologies. The current mobile communication technologies intensification had equally brought the unavoidable multiplications in the ratio of the base service stations which also had raised the public concern over the considerable health hazards of the radioactive emissions from the communication systems. Notwithstanding the assurances of the several regulatory agencies, the World Health Organization and service providers, confirming compliance and strict observance to the international exposure standards in implementation, the apprehension over the electromagnetic spectrum emission is increasing. To that effect, the International Commission on Non-Ionizing Radiation Protection (ICNIRP) had made recommendations that established the intensities of the radio frequency (RF) exposures which are considered harmless to the community of users. This paper assessed the radio frequency radiation from mobile base stations in some selected states in north western Nigeria. The methodology employed for the study is measurement and instrumentation method. Handheld spectrum analyzer (Aaronia HF 4040V3) and a wheel meter were used for the measurement of electromagnetic emissions from selected Airtel, Glo, MTN and Etisalat base stations at capital city of Kano, Jigawa and Katsina states respectively. It was found …
