Abstract

Overview

The study focuses on the impact of electromagnetic (EM) radiation from near-field and far-field sources on human organs, analyzing how different radiation patterns and frequencies affect temperature changes in the body.

Key Findings

• The pattern of field radiation and the operational frequency of EM sources notably affect the temperature distribution within organs.
• Increases in the temperature of testis are observed but are below the infertility thresholds even for high frequencies such as 900 and 1800 MHz.
• For proximities less than 2 meters, the specific absorption rate (SAR) exceeds the safety exposure limits set by the International Commission on Non-Ionizing Radiation Protection (ICNIRP).

Conclusion

The research underlines the importance of understanding the impact of electromagnetic field exposure on organ temperatures to formulate relevant safety regulations and exposure limits. The study presents a computationally driven analysis involving SAR and heat transfer in human torso models, specifying how tissue dielectric properties further influence these patterns. Establishing accurate exposure limits for the power output of wireless transmitters and their safe distances from humans is crucial.
