![]() ![]() Source of these waves or are exposed to these waves in the workplace. The results of studies about physical and even psychological problems of radar waves on human health have caused great concerns for those who live near the Resolving these concerns can have a significant impact on improving people’s quality of life [ 11 On the other hand, aging and chronic diseases of the body are the fundamental challenges which affect the quality of human life. ![]() In spite of the many reported hazards, associated with radar radiation exposure,Īpplications of such systems are increasing [ 6 Radar systems have been widely used in navigation,Īerospace, communication systems, and meteorology applications. Radar is a radio frequency wave detector used to observe and measure the distance, angle or velocity of objects. The electric properties of all tissues have been practically measured and known [ 1 The results show that for this normalized source, the safety criteria have been respected, but for a higher source, the calculations must be repeated. In addition, the maximum Specific Absorption Rate (SAR) for each case has been calculated. On the other hand, the higher frequency can cause a higher risk to the human skin. Results: Total body absorbed doses for 4 GHz, 8 GHz, and 12 GHz frequency, and 6 min, 4 h, and 30 days exposure time, have been calculated as 1.136×10 -5, 1.598×10 -5, 1.58×10 -3, 1.521×10 -5, 3.122×10 -5, 4.52×10 -3, 4.1×10 -5, 10 -4, and 10 -2, respectively.Ĭonclusion: It has shown that the internal organs of the body and head will be under more risk by reducing radar frequencies from 12 GHz to 4 GHz. ![]() The exposure dose limitations have been considered using the International Commission on Non-Ionizing Radiation Protection (ICNIRP) safety and health guide report. Furthermore, various physical and electrical properties of each tissue and organ for different frequencies and exposure times have been studied. Material and Methods: In this simulation study, an adult body model versus 1 watt source with a distance of 50 centimeters exposure has been simulated using the CST STUDIO SUITE. Objective: This study aims to evaluate the risk of radar wave exposure and to explore the effects and limitations. However, engineering department’s staff various tissues are always under chronic radiation generated by the radar fields which may affect health. Background: The application of radar systems in telecommunications and aerospace science is important. ![]()
