Temperature Increase and Specific Absorption Rate Distribution in Human Breast from Cell Phone Radiation

Abstract

Overview

This study investigates the effects of cell phone radiation on both healthy and unhealthy female breast tissues. The aim is to develop safety criteria and enhance cancer detection technologies.

Methodology

• A computational model is used to simulate radiation at 900 MHz and 1800 MHz frequencies.
• The model involves a sphere-shaped breast including cancerous tissue configurations.
• The study utilizes thermal investigation via the heat transfer equation to determine temperature changes and specific absorption rate (SAR) modifications in the tissues.

Findings

Initial tests were conducted by exposing healthy breast tissues to radiation from an antenna at varying distances. Subsequently, temperature and SAR distributions were assessed on different radii within cancerous breast tissue positioned variously within the breast.

The results underscore increasing temperature and SAR levels correlating with tumor size while showing a decrease as the radiation source is positioned further from the tissue.

Conclusion

Increased tumor size is directly associated with higher levels of radiation absorption and elevated temperature within the breast tissue, suggesting a definitive risk to breast health from proximity to radiation sources. These findings reinforce the need for rigorous safety standards and proximity guidelines in the use of mobile phones.
