The last decade has witnessed a remarkable growth in all aspects of modern technology such as mobile phones, wireless communication links, antennas, microwave ovens, and high voltage transformers which are sources of electromagnetic radiations (EMR). This research work investigates the effect of exposing building occupants to electromagnetic emission from high voltage transformers. The sample of this study is 150 students comprising 78 males and 72 females. Spectra RF3040 was used to measure magnetic flux density in the five schools used for this research. Measurements were also taken to determine the effects of electromagnetic emission on student's tympanic temperature, blood oxygen saturation, heart pulse rate and arterial blood pressure (diastolic and systolic). Tests on health situations were done indoor four times at (9:00 – 9:30) a.m. and four times at (1:30 – 2:00) p.m. each day. The results show from analysis that the measured values of power flux density were within slight concern limit. The gradual increase in tympanic temperature, heart pulse rate, and arterial blood pressure is an indication that EMR has adverse health effects on building occupants within 200m distance from such transformers. Recommendations were given.
