| Nowdays, with the development of science and techonology and improving people’s living standard, a large number of electronic products are producted and used, and the rapid development of urbanization, people’ living enviroment is overflown with electromagnetic radiation. How to determine the effect of electromagnetic radiation in environment on human’s health is one of the major issues studied by many scholars. The effect of extremely low frequency electromagnetic fields and far-infrared light were studied by the infrared spectral characteristics, fluorescence spectroscopy and electrical properties changes in physical properties of the different tissues of rats. The main work of this thesis is summarized as following:First, we established a high cholesterol rat model, which was verified by measurements of total cholesterol and triglycerides. Characteristics of infrared spectral, fluorescence spectral and electrical properties of the rat model of high blood cholesterol and the control rats are measured. The results show that from the physical point of view the high blood cholesterol rats are different from the normal grop.Second, the physical characteristics of high cholesterol rat tissues (testis, liver, serum, brain) are studied. Infrared spectroscopy, fluorescence spectroscopy and electrical characteristics of blood, brain and testis of experiment group which were expousued by extremely low frequency electromagnetic fields are measured. Further analysis revealed that extremely low frequency electromagnetic field exposure can affect blood, nervous and reproductive system.Third, the physical properties in testis, liver, serum and brain of high cholesterol rats expousured by millimeter-wave are studied. Some potential impact of millimeter-wave exposure on high cholesterol rats are analyzed. |
