Introduction: Communication between mobile phones and antenna BTS (Base Transceiver station) is carried by electromagnetic waves. Energy associated with these waves can be absorbed by biological tissues. so Widespread use of these devices has generated public concern about exposure to electromagnetic waves. In this study the electric field intensity and specific absorption rate in the radiology, emergency, general hospitalized and diagnostic laboratory departments was obtained in Arak, IRAN
Materials and Methods: In this study, using radiometer (TES 592), the electric field measurements were performed in two modes of average (Average = Avg.) And Maximum Average (Max. Avg.) For six minutes in accordance with the recommendations of the ICNIRP and IEEE Committees in the 900 MHz frequency. then using the equation Specific Absorption Rate induced in brain, skin, fat and bone tissues were calculated and compared with the thresholds recommended by the International Commissions
Results: The results showed that the mean value of the electric field was 1.334 V/m which is almost 2.7% threshold introduced by International Commission on Non-Ionizing Radiation Protection (ICNIRP) and 2.6% threshold adopted by the Institute of Electrical and Electronics Engineers (IEEE). The highest SAR value was calculated 1.6W / Kg for skin that is lower than the threshold values of ICNIRP(2W/Kg) and IEEE(1.6W/Kg)
Conclusion:The results of the present study showed that for both quantities in Arak hospitals the values greater than the threshold announced by committees such as IEEE and ICNIRP are not observed. To deal with the concerns of the community that is generally caused by a lack of awareness the educational and public awareness programs should be developed
