Introduction: Mobile communications developed into an integral component of our daily life. The growing demand for mobile communication services in Kuala Nerus has seen an increase in the installation of base station towers (BST) in residential areas, as well as near schools, and hospitals. Kuala Nerus was selected as a study location because it is a newly developed district in Terengganu, hence, it is crucial to perform electromagnetic radiation (EMR) measurements in the early stages. Objective/aim: This study aimed to measure the RF EMR exposure level in residential areas in Kuala Nerus by measuring the strength of its electric field (EF) strength and power density (PD) value while comparing it with the ICNIRP’s standard guidelines. Materials and methods: Measurements were made using NARDA NBM 550, connected to a probe that could detect frequencies from 100kHz to 6GHz. The data collection period for each point was approximately 6 minutes during daytime. Results: Average radiation levels in terms of EF strength at all locations were found to vary between 0.26 (V/m) to 3.35 (V/m) (PD value about 0.02 µW/cm² to 2.97 µW/cm²). The highest level was measured at Surau Kg Pok Tuyu, which was 5.48% or 18 times lower than the MCMC exposure limit for public areas. Conclusion: The RF value obtained does not exceed the standard limit, which in turn contributes indirectly to health monitoring initiatives for public NIR exposure. This study found that exposure levels in selected BSTs in residential areas in Kuala Nerus were within the standard guideline limits.
