Is substation radiation harmful to human body?

I am very happy to see this topic, because I come from radar. No matter in the space radiation range of wires or radios, there is radiation, which may cause radiation damage. However, this kind of harm is far from as powerful as imagined. First of all, as mentioned above, the radiation measured in most areas is still lower than the radiation received by the human body. There is no direct evidence that it may cause some kind of harm to human body, just like friction and static friction. If the static friction is not exceeded, the object will not move. The electromagnetic wave does not exceed an acceptable standard, and the reaction time cannot be reached, so it will not cause real harm. Secondly, the so-called test problem, I have worked and tested many times in the ultra-strong radiation area for a long time, which has a lot to do with the test method. The radar I use is more powerful than the sixth power of MW, 10, which can easily kill any mammal. But in fact, my colleagues and I are alive and well. Because, in fact, the electromagnetic waves emitted by the equipment are rarely carried out in a high-power continuous way, and generally work in a pulse way. If you measure in practice, there may be many results: if you measure the peak value, then this value may be very high, which is particularly scary; If the sampling time is a little longer during measurement, the value may drop by several orders of magnitude. Take my original equipment as an example, the peak value is alarmingly high, but the measured data is three or four orders of magnitude lower than this data. Third, the directivity and attenuation of electromagnetic radiation. Electromagnetic wave has strong directivity, especially for electromagnetic equipment with antenna. For example, 99.99% of radar energy is concentrated on its axis, and the power of sidelobe is very low, which can be ignored in many cases. Other devices that can radiate electromagnetic waves also have corresponding lobe patterns, and the radiation intensity is the highest only in the direction of the main lobe. As for attenuation, the radiation ability of electromagnetic waves is inversely proportional to the cubic power of distance. It can be said that once it is emitted, the energy drops sharply (so the wireless transmission of electric energy mentioned in my other post is too wasteful and difficult). In other words, as long as the distance is slightly increased, the radiation can be greatly reduced. Fourth, several situations that cause harm. I've seen several cases of radiation injuries, and I have them myself. At that time, no protective measures were taken, and direct observation of the radiation source for a long time led to corneal inflammation. Later, every time I deviated from the beginning, I looked directly after connecting the line, and there was no problem. That's a watt-level radiation source, not a microwatt. Some of my relatives were irradiated by mobile phones. There is a simple reason. At that time, there were too few mobile base stations, and the power of mobile phones was high. It took more than 5 hours to talk every day, which led to migraine. Later, I changed my mobile phone and the talk time was reduced. There is no problem at all. A friend once worked in a radar testing ground, where many radars were often turned on at the same time, which caused the ostrich in the nearby ostrich farm to shed hair (the ostrich farm was run by spies and specialized in collecting radar data and other information), but the local people, including the experimenters, were fine, which was related to the adaptability of the animals themselves, and ostriches could not be hidden. Fifth, the psychological effect is terrible. Some colleagues also think that they have been injured by radiation, claiming that they have caused problems such as being unable to lift. In fact, my colleague's work place is mainly in a shielded room, and he has no contact with radiation at all, which is a psychological effect. He has read too many books about radiation damage. As long as someone says that the radar has started to emit electromagnetic waves, even if the radar is not turned on, he feels sick, shivering and sweating. Another friend called me after a while and asked if there was a cell phone base station near my home and a transformer not far away. He felt numb at the sight of that thing. However, in actual measurement, due to the need of antenna lobe design, the mobile base station is often dark under the lamp, and the electromagnetic radiation next to the base station is not the strongest. Some people say that you say that electromagnetic waves are not strong, so why is the cell phone signal so good? In fact, the key to a good cell phone signal lies in the receiving equipment, and its core technology is the low-noise first-stage amplifier. Due to the radiation effect of spherical waves, it is difficult to obviously increase the radiation distance of electromagnetic waves only by increasing the transmission power. Radiation from transmission lines exists, but it depends on voltage. The radiation capacity of 220V used in residential areas is very limited. Only when you are close to a 10,000-volt high-voltage line will you feel your hair stand on end. Therefore, the damage of electromagnetic waves is not as terrible as imagined. Even if there is no equipment to radiate electromagnetic waves, electromagnetic waves in space are normal. First, we should know how to reduce and avoid electromagnetic radiation, distance ourselves from high-power electromagnetic equipment, such as radar, such as microwave station, and don't stay and live in its radiation direction for a long time. However, the radiation power of mobile signal base stations we see every day is within the acceptable radiation range of human body. Second, have a good attitude, understand it, don't be afraid of it, and use it correctly. Don't feel nervous and hurt when you see something that can radiate electromagnetic waves. Sometimes, as people say, drinking too much water is poisoning, and it takes a lot to happen. Some people are still afraid of refrigerator radiation. Actually, who will hold the refrigerator when it is working? For example, mobile phones, radiation damage has not been confirmed, but the shorter the call time, the better. The third is to have good working and living habits. Many people say that I was injured by computer radiation, but it is actually false. It is because of the physical discomfort caused by using the computer in an incorrect posture for a long time, such as cervical problems and lumbar problems. Some have the same headache as using a mobile phone, and many times it is also because of posture problems, causing local muscle tension. For example, microwave ovens, although there is almost no radiation leakage because of the improvement of design technology, should not stay around for a long time after opening.
