چکیده
Background and Aims: Exposure to electromagnetic fields occurs as a result of electronic equipment exploitation. The aim of this study was to evaluate the exposure to electromagnetic fields and its impact on the public health of computer users.Materials and methods: The present cross-sectional study involved 73 male employees. A calibrated gauss meter (model HI-3603, USA) was employed to measure the intensity of electromagnetic fields. A general health questionnaire was also used to assess the health status of the operators. T tests and chisquare test were used for data analysis. Ethical issues were all considered in all stages of the study, and required permission were received.
Results: The electric field intensity range of desktop and laptop displays were measured 0.26 - 1.2 and 0.28 - 0.87 v/m, respectively. The corresponding intensity at a distance of 30 cm from desktop displays was 1.2 v/m; which was more than the standard level. Indeed, general health questionnaire results revealed that 39% of computer users suffer from the lack of public health. The public health status between two groups was significantly different (p<0.001).
Conclusion: Exposure duration factor is not considered in exposure level standards for electromagnetic fields, and a ceiling amount is only reported. According to the results of this study, electromagnetic field intensity values were below standard limits at most of the measured points; however, given the long duration time of equipment usage, the health consequences of this exposure could be accounted as cumulative exposure.
