Do electric fans emit radiation?

Haha, there is radiation. At least the operation of the engine produces thermal radiation, which is transmitted to you with the wind! ---------Mobile phone radiation is low-frequency radiation, and its power is not big, so it's nothing! As for the mode you use, it's the same! Mobile phones work on the principle of transmitting and receiving electromagnetic waves and convert the received electromagnetic signals into sounds or sounds into electromagnetic signals. Electromagnetic waves themselves are radiation! Therefore, there are two aspects of mobile phone radiation: 1, it is the mobile phone and 2, it is the electromagnetic waves emitted by the base station in the service area. However, electromagnetic radiation from cell phones is not nuclear radiation, so don't worry! Answering questions about radiation is notnot flattering, but I want to pass on some knowledge to others, but no one applauds me. My knowledge is limited and my powers of persuasion need improvement! 1. Physical Definition: Objects with temperatures above -273 degrees Celsius (absolute zero) radiate (infrared heat)! The human body is a standard radiator that constantly emits infrared rays. Radiation exists everywhere in life, so it cannot be avoided! But you have to protect yourself from nuclear radiation, because if you don't protect yourself, you will become deformed! But it is rare to encounter nuclear radiation in life! 2. Radiation is made up of light waves! Sunlight contains all radiation, and it is the atmosphere that protects us from exposure to harmful radiation! Radiation can be simply divided into: 1. Visible light radiation (the visible part of the light from thesunlight to the naked eye). They have a physical thermal effect on the human body, which means that their absorption only generates heat on the human body! We've all been in the sun. 2. Invisible radiation with a frequency lower than “visible light”. They have the same physical thermal effect on the human body as “visible light radiation”. That is to say, the radiation from computers and cell phones is weaker than the sun to which you are exposed! There are also powerful ultraviolet rays (of a frequency higher than visible light) present in sunlight that enters the atmosphere. Many sunscreens protect against ultraviolet rays! 3. Invisible radiation with a frequency higher than "visible light" is called nuclear radiation. It has a chemical effect on the human body and directly harms the human body!

-----The above distinction isdue to the fact that "frequency x wavelength = speed of light", and the speed of light is constant, so high frequency means short wavelength, and short wavelength means strong penetrating power! 1. The human body can actually tolerate a certain amount of nuclear radiation. Up to this amount, it will not affect the correct copying of our genetic information. This is why we can go to the hospital for a fluoroscopy! The X-rays emitted by medical X-ray instruments are nuclear radiation rays! If it is too much, the human body will be unable to copy the genetic information correctly due to damage to the genetic information in the DNA, leading to mutations and the possibility of cancer! 2. Computers and other electrical devices do not emit radiation with a frequency higher than “visible light”! But this does not mean that b-radiationquite frequently are harmless to the human body, it is still a question of quantity! For example, sleeping on an electric blanket and setting the temperature too high can cause burns to the human body! And low frequency environments can disrupt the balance of the human body and lead to the risk of cancer. However, low-frequency environments probably refer to places such as high-voltage substations, and cannot be caused by multiple computers or household appliances! The standard methods to combat radiation are as follows: 1. Shield the radiation source Generally speaking, lead is the best shield, so nuclear materials are all lead containers! 2. Protect the irradiated body and radiation-resistant clothing (the material is unknown, but it is estimated to be Possible for filling) that's it! -----Shielding means shieldingitem packaged. Radiation is a light wave, 300,000 kilometers per second, if leaked, the radiation can fill a certain intensity space through reflection in one second! -----So those who say that the use of plants, radiation resistant (definitely not protected) maternity clothing, radiation elimination devices, etc. are wrong. to eliminate or prevent radiation is not scientific! 1. Evolution has determined that plants on earth only need appropriate "visible light waves" to participate in their own photosynthesis, and will not absorb or reflect unnecessary light waves. For example, green plants become green plants to our eyes because they do not absorb or reflect green light waves! The radiation from electrical or nuclear devices is undoubtedly invisible. Because these invisible light waves, if plants absorb them, will only produce physical heat.if that ! It cannot be used for photosynthesis. Have you ever seen plants growing in the dark? ! Some materials absorb heat better! But plants, especially desert ones, would have to be relatively weak at absorbing heat, because it's the sunlight in the desert that makes them look so strange. The fact that cacti do not have leaves is because they are afraid of sunlight and loss. of water. Fast and advanced! That is to say, the cactus is actually a master of sun protection and anti-radiation absorption rather than a master of radiation absorption, because the absorbed radiation will be converted into heat, this which will either cause it to ripen in the sun or cause water loss! So it’s ridiculous that cacti are resistant to radiation!

2. Regarding anti-radiation maternity clothing, it's very simple, we don't pack them too tightly! (Recently, a small crack appearedue in a protective device containing nuclear fuel rods in the core reaction device of the national nuclear power plant. Fortunately, the protective device has three layers and there is no radiation leakage! You should know that nuclear radiation can be caused by hair wire crack. )

3. Unless it's a small black hole, how do you eliminate the radiation? ! To eliminate nuclear radiation, we usually collect the irradiated soil and transport it to a landfill! ----------Excerpts are allowed, but must be noted--------------
