Abstract

Tissue response to radiation is important, and can be used as indicator to determine the damage degree due to radiation, and therefore can help in medical diagnosis that leads to affective therapy. In this paper, the electro-biological impedance, and radiation effects on rates kidney tissues is studied over a frequency range (300 Hz- 5 MHz), with x-ray exposure doses (0.5 – 6 Gy), and in different time periods (1, 2, 4, 16, 23, 30 days). The data were computationally fitted to the selected models, and the necessary parameters were calculated for the Cole-Davidson model. The characteristic frequency is obtained for all samples, and finally, its trend with dose and time is explained. Further investigations are required to help radiation therapy management and limit the excessive dose exposure, and time in medical trial.
