Nowadays, the wireless technology has become a lifestyle; even the children have their own
mobile phones, although they are categorized as high risk susceptible to health problems
due to radiation. Thus, the public exposure that stemmed from electromagnetic radiations
become public concern since studies have been done and the finding showed that the repetitive
and long term exposure may have adverse health effect. This study was conducted to
evaluate the exposure level at UMT and UniSZA campuses by measuring the electric field
strength. This measurement was conducted using omni-directional antenna below 4 GHz,
connected to spectrum analyzer. In this paper, the measured values are compared with
the previous study from several locations and then the spatial maps of exposure level are
developed. The result shows that high exposure level was recorded at UMT and UniSZA.
From this study, the findings may assist the Ministry of Health to monitor the public health
due to non-ionizing radiation (NIR) exposure. This is crucial to make sure the international
commission of non-ionizing radiation protection (ICNIRP) limit is complied. Moreover, the
development of public NIR exposure policy can be initiated to the Malaysia government for
health concern. For future study, the investigation of the suitable material used as antenna
and casing or exposure reduction tool can be done to reduce NIR exposure rate on human
body.
