This study describes an evaluation of Electric Field (EF) strength around Gong Badak located at Kuala Nerus, Terengganu. This area was selected because it is categorized as residential area and the population density is high due to its location nearby learning institute (Institute of Industrial Training Gong Badak). Spectrum analyzer connected to an omni-directional antenna was used to measure the EF strength. The measurement was obtained for 10 minutes for each 26 selected points. The data was then analyzed to determine the highest EF exposure level detected at each site. The spatial model of EF exposure using GIS software was then developed to get the map of exposure. The value of highest exposure was compared with the permitted limit recommended by ICNIRP and previous study. From the analysis, it can be concluded that the exposure level at selected area were still below the ICNIRP limit. However, the value is quiet high which is approximately 25.05 V/m peaked at 2137.5 MHz. The results of this study will complement existing studies that have been done at around Kuala Nerus area. This exposure map can be used to propose the government to revise the policy and guidelines for non-ionizing radiation safety. The Ministry of Health Malaysia may utilize the map to monitor the EF exposure in this country for public health purpose. © 2019, Indian Journal of Public Health Research and Development.
