The nervous system is highly sensitive to microwaves. Repeated exposure to low-intensity electromagnetic radiation will change the function of the central nervous system, resulting in neurasthenia and other symptoms, mainly manifested as dizziness, lethargy, fatigue, decreased memory and increased slow waves in EEG. Besides neurasthenia, the biggest feature of electromagnetic radiation is that it makes the autonomic nerve function disorder.
2. Effects on cardiovascular system
Under the action of microwave, hemodynamic disorder, vascular permeability change and ECG change often occur. The blood pressure of people exposed to microwave for a long time decreased, but some of them increased. Electrocardiogram analysis shows that besides bradycardia, there are tachycardia, sinus arrhythmia, atrial or ventricular premature beats, and changes of heart and skin ischemia under ST segment depression and T wave depression. While others may develop autonomic neurovascular dysfunction.
3. Effects on eyes
The human eye's crystal is vulnerable to electromagnetic radiation, and its internal blood flow is small, so the temperature is extremely high under electromagnetic radiation. Experimental research shows that microwave radiation can cause cataract, and its threshold is about1100mw/cm2 for single irradiation and 80mW/cm2 or lower for repeated irradiation. High-intensity electromagnetic radiation can also damage cornea, iris and anterior chamber, resulting in vision loss or complete loss.
4. Effects on reproductive system
According to the hygienic investigation, after long-term microwave operation, men may have impotence and sexual dysfunction, and women may have menstrual disorders. High-intensity microwave radiation may also cause miscarriage in pregnant women. In addition, microwave radiation may also lead to glucose metabolism disorder and female secretion function decline.
Characteristics of microwave radiation:
1, microwave, contrary to infrared, is an important radiation characteristic of objects at low temperature. The lower the temperature, the stronger the microwave radiation.
2. The intensity of microwave radiation is much weaker than that of infrared radiation, and it needs to be processed before it can be received by the receiver.
3. In the application of remote sensing technology, the difference of microwave radiation between different ground objects is greater than that of infrared radiation, so microwave can help identify ground objects that are difficult to identify in visible and infrared bands.
4. The frequency of microwave is 300MHz~300GHz, which is located between infrared radiation light wave and radio wave of electromagnetic wave, and can only excite molecular rotational energy level transition.
