Analysis of biological effects of cell phone radiation on human body using SAR

Abstract

Overview

The intersection of health and technological progress, especially with the widespread use of cellular phones, has raised significant public concerns about potential health hazards from electromagnetic energy absorption. This study critically evaluates the implications of cell phone radiation on human health using detailed scientific methods.

Findings

• The research utilized the ANSYS 3D human body model to measure the Specific Absorption Rate (SAR) across different tissues by altering antenna distance and power.
• Temperature increases in human tissues are directly related to the radiated power of the antenna. Low power (less than 125 mW) results in minimal temperature rises, while high power (1 W) leads to significant increases.
• SAR values remain below safety limits at lower frequencies and powers, but exceed these limits significantly at higher frequencies and maximum power settings.
• The relationship between SAR values and frequency suggests an enhanced risk of tissue damage at higher frequencies and power levels.
• Increasing the distance between the antenna and the head reduces SAR values, mitigating the potential risks.

Conclusion

The long-term exposure and worst scenarios examined suggest that while there are increases in temperature, these are not yet at levels considered immediately dangerous. However, caution is advised as higher powers and frequencies pose increased risks.
