Mechanism of electromagnetic radiation
- Nov 20, 2018 -

The mechanism of electromagnetic radiation harming the human body is mainly thermal effect, non-thermal effect and cumulative effect. The thermal effect means that the water molecules in the human body are rubbed by electromagnetic waves and rub against each other, causing the body to heat up, thus affecting the normal work of the internal organs. Water is an important part of the human body, and biological water has a strong dipole. When the human body is in an electromagnetic field, the polar molecules of the human body (such as water) have a certain orientation under the action of an electric field (forming a dipole), that is, the polar molecules arranged in a disorderly state under natural conditions are arranged according to the anode and the cathode, that is, Produce an orientation movement. In the case of alternating current electromagnetic waves, polar molecules will line up and down as frequency changes. In this way, when the molecules move, they collide with each other to generate heat. When the alternating frequency is high, the generated heat cannot be lost, and the temperature of the body rises to exhibit a thermal effect. The higher the electromagnetic oscillation frequency, the more intense the molecular orientation in the body, the more prominent the thermal effect, and the more serious the damage. When the electromagnetic wave energy absorbed by the human body reaches a certain intensity, the human body will be heated and a high temperature physiological reaction occurs. In severe cases, the human body will have lesions such as neurasthenia and leukopenia. The non-thermal effect means that there are weak electromagnetic fields in the organs and tissues of the human body. They are stable and orderly. Once they are disturbed by the external electromagnetic field, the weak electromagnetic field in equilibrium will soon be destroyed and the human body will suffer damage. When the human body is exposed to electromagnetic radiation with little intensity for a long time, although the human body temperature does not increase significantly, it will cause resonance of the human cell membrane, and the membrane potential changes, which limits the mobility of the cells. Therefore, the non-heating effect is also called the "resonance" effect. When the electromagnetic wavelength exceeding a certain intensity acts on the human body for a long time, although the temperature of the human body is not significantly increased, it causes resonance of the human cell membrane and limits the mobility of the cells. This effect at the molecular and cellular level is both complex and delicate, leading to physiological reactions such as changes in heart rate, blood pressure, and insomnia and forgetfulness. Cumulative effect means that the thermal effect and the non-thermal effect act on the human body, and the damage to the human body has not yet reached before the self-repair (usually referred to as the human body's endurance - internal resistance), and if it is again subjected to electromagnetic wave radiation, the degree of damage will accumulate. It will become a permanent morbidity and endanger life
