Effects of 1.8GHz electromagnetic radiation on dielectric properties of SD Rat's typical tissues

With the progress of modern science and technology, the impact of electromagnetic radiation on biological health condition is increasing. The influence and the mechanism of interactions between electromagnetic radiation and biological tissues are urgently to be studied. In this paper, the variation of dielectric properties of 4 typical SD rat tissues (muscle, liver, kidney, heart) with irradiation of fixed parameters and without irradiation was investigated. For the test group, SD rats were irradiated 8 hours per day for 1-3 days, by a 200W radiation source of 1.8GHz, while the control group was under the same condition except irradiation. The experimental results show that, comparing with the control group, dielectric parameters of the test group produced certain changes, and effect of different radiation dose varies. Meanwhile, blood routine test results of SD rats for both groups were in normal physiological index. After irradiation process, the normal physiological activity of SD rats in both groups could be recovered in a short time. In a high-power radiation condition, the dielectric properties of SD rat tissues would be changed depending on the irradiation time of occurrence and its physiological characteristics like blood also had an abnormal indicator. The results of dielectric properties after irradiation can be used for further study of health effects of electromagnetic radiation on organisms, and provide theoretical analysis and experimental basis for understanding the relationship between electromagnetic environment and human health.
