مطالعه میدانهای الکترومغناطیس تلفن های همراه متداول و برخی علائم خود گزارش شده کاربران

Introduction: Many calls already perform by cell phones that have need to radiation exposure by users. Because of health reasons and some doubts about effects, this study was conducted to determine the extent of the mobile phones radiations and self report symptoms of users. Material and Method: In this cross-sectional study, 80 available randomly users contain students and staffs of Hamadan University of medical sciences in 2012 were selected. Electro Smog meter TES-593 was used as radiation measurements tool. In order to assess health effects of mobile phones’ radiation, a self-administered survey questionnaire were used. Statistical analyses were performed using T-test, ANOVA and X2 tests by SPSS 11.5. Results: Results showed that the conversation mode had a highest level of electromagnetic indices in the studied cell phones. Compare means of power density that emitted from studied mobile phones had significantly difference (P=0.001). Relationship between exposure to the mobile phones radiation by symptoms of head-ache, anxiety and sleep disturb were significant (P=0.02, P=0.03, and P=0.002 respectively). Conclusion: Although, there is founding the relations between exposure to cell phones electromagnetic fields and some self-reported symptoms in line with same reports, These symptoms can not be absolutely attributed to the use of mobile phones. With these considerations it is recommended that for prevention of health risks from cell phones, safe type selection, control of call duration and frequency of use of these devices should be mentioned.
