Abstract:
Background: The application of radar systems in telecommunications and aerospace science is important. However, engineering department’s staff various tissues are always under chronic radiation generated by the radar fields which may affect health. Objective: This study aims to evaluate the risk of radar wave exposure and to explore the effects and limitations.Material and Methods: In this simulation study, an adult body model versus ۱ watt source with a distance of ۵۰ centimeters exposure has been simulated using the CST STUDIO SUITE. Furthermore, various physical and electrical properties of each tissue and organ for different frequencies and exposure times have been studied. The exposure dose limitations have been considered using the International Commission on Non-Ionizing Radiation Protection (ICNIRP) safety and health guide report. Results: Total body absorbed doses for ۴ GHz, ۸ GHz, and ۱۲ GHz frequency, and ۶ min, ۴ h, and ۳۰ days exposure time, have been calculated as ۱.۱۳۶×۱۰-۵, ۱.۵۹۸×۱۰-۵, ۱.۵۸×۱۰-۳, ۱.۵۲۱×۱۰-۵, ۳.۱۲۲×۱۰-۵, ۴.۵۲×۱۰-۳, ۴.۱×۱۰-۵, ۱۰-۴, and ۱۰-۲, respectively. Conclusion: It has shown that the internal organs of the body and head will be under more risk by reducing radar frequencies from ۱۲ GHz to ۴ GHz. On the other hand, the higher frequency can cause a higher risk to the human skin. In addition, the maximum Specific Absorption Rate (SAR) for each case has been calculated. The results show that for this normalized source, the safety criteria have been respected, but for a higher source, the calculations must be repeated.
