Abstract

Temperature Increase and Specific Absorption Rate Distribution in Human Breast from Cell Phone Radiation Kunter, FC, Gündüz C, Seker SS. Temperature increase and Specific Absorption Rate distribution in human breast from cell phone radiation.J Med Imaging Health Informatics. 8(6):1186-1191. DOI: 10.1166/jmihi.2018.2418. Aug 2018. Abstract This study describes the cell phone radiation effect on the healthy and unhealthy female breast tissue to establish safety criteria and to detect the cancerous tissue. A computational modeling is performed at 900 MHz and 1800 MHz with a sphere shaped breast and cancerous tissue in different configurations. Thermal investigation is performed through the heat transfer equation to determine temperature and specific absorption rate elevation in the female breast tissue. First, healthy breast tissue is excited with an antenna of which distances to the breast is varying. Next, the distribution of temperature and specific absorption rate are estimated on the different radius of cancerous breast tissue which is located at the center and at the bottom of the breast, respectively. The simulated temperature and the specific absorption rate values imply that the values are ascending with the size of the tumor whereas descending as the source is positioned further. ingentaconnect.com

Main findings

Computational modeling at 900 MHz and 1800 MHz estimated temperature and SAR in a sphere-shaped breast model with cancerous tissue in different configurations. Simulated temperature and SAR increased with tumor size and decreased as the antenna/source distance from the breast increased.

Outcomes measured

  • specific absorption rate (SAR) distribution in breast tissue
  • temperature increase in breast tissue

Limitations

  • Computational/simulation study (no human or animal measurements described)
  • Breast modeled as a sphere-shaped geometry
  • Exposure described as an antenna with varying distance; specific real-world phone use conditions not detailed in abstract
  • No quantitative SAR or temperature values reported in the abstract
