Abstract

Introductin: The advent of COMPUTERs, VISUAL DISPLAY TERMINALS and their capabilities have gradually resulted in an increase in their use and user population. The use of these devices have created new hazards for their operators, namely exposure to their electromagnetic field (EMF). Therefore, assessment of this hazard and monitoring of operators' health is necessary. Material and Methods:This study was of a descriptive-analytical type. In this study, EMF around 80 monitors was measured at various distances in the of Medical School of Hamadan University using HI-3603 survey meter. 50 COMPUTER operators wereselected as the case group and another 61 were selected as the control group. The data concerning the signs of CHRONIC FATIGUE SYNDROME (CFS) were collected by use of questionnaires for both groups. The statistical test of t-test and χ2 were used for the analysis of the results. Results:Results indicated that in 97.7% and 27.5% of cases, at distances of 30cm and 50cm from the monitors respectively, the intensity of the magnetic field was greater than 20mA/m, respectively. In 28.7% and 10% of cases at distances of 30 cm and 50cm, the intensity of the electric field was greater than 2.5 V/m respectively. It was found that there was a relationship between the type and the life span of monitors (P<0.05). A comparison of the signs of CFS between the case and control groups indicated that there was a higher prevalence of lacrimation (P<0.001), headaches (P<0.001) and dizziness (P=0.002) in the case group. Conclusion: While operating a computor, it is recommended to keep a mininum distance of 60 cm away from it.
