Human Health Risk Assessment of 4-12 GHz Radar Waves using CST STUDIO SUITE Software

Abstract

Overview

This study explores the health risks associated with exposure to 4-12 GHz radar waves using CST STUDIO SUITE software, highlighting potential effects on human tissue and organs during varying exposure times.

Objectives

• Evaluate the health risks from radar wave exposure.
• Explore the effects and limitations.

Methods

Simulations were carried out using an adult body model with 1 watt source at 50 centimeters exposure. Physical and electrical properties were calculated for different tissues and organs at varying frequencies and exposure times, respecting the ICNIRP safety guidelines.

Findings

• Internal organs and the head are at higher risk at lower radar frequencies from 12 GHz to 4 GHz.
• Higher frequencies potentially increase risks to human skin.
• Specific findings on the Specific Absorption Rate (SAR) have been calculated and discussed.
• Risk assessments indicate that all standard safety criteria have currently been met.

Conclusion

The simulation study articulated that the radar wave’s influence on human health varies inversely with frequency increase, suggesting a severe impact on vital organs at lower frequencies and prolonged exposure. Conversely, higher frequencies pose an increased risk to skin integrity, emphasizing the need for continual evaluation in occupational settings involving prolonged radar exposure.
