This type of radiation is radio electromagnetic wave radiation. Electromagnetic waves are everywhere. Even if the radiation is 20 to 30 meters away, the radiation still exists and is stronger than usual.
The intensity needs to be calculated with more detailed information, such as the inherent properties of the metal, nearby electromagnetic field conditions, emission frequency, specific wave bands, etc.
Here I will just explain that compared with nuclear proton radiation, nuclear electron radiation is easier to deal with electromagnetic wave radiation. 1. Understand the common sense about electromagnetic radiation. Learn preventive measures and strengthen safety precautions.
2. Do not place household appliances too close together or use them together frequently to avoid exposing yourself to the risk of excessive doses of radiation. In particular, TVs, computers, refrigerators and other electrical appliances should not be placed centrally in the bedroom.
3. Various household appliances, office equipment, mobile phones, etc. should be avoided for long periods of time.
4. When electrical appliances are suspended from use, it is best not to leave them in standby mode. , because a weaker electromagnetic field can be generated at this time, and radiation accumulation will also occur for a long time.
5. A certain safe distance should be maintained when using various electrical appliances.
6. If consumers are exposed to excessive doses of electromagnetic radiation for a long time, they should take the following self-protection measures:
(1) Live and work in high-voltage lines, substations, and radio stations , people near TV stations, radar stations, electromagnetic wave transmission towers, patients wearing pacemakers, people who often use electronic instruments, medical equipment, office automation equipment, and people living in modern electrical automation environments, especially those with resistance Weak pregnant women, children, the elderly and sick patients should be equipped with shielding protective clothing against electromagnetic radiation if possible to block electromagnetic radiation from the body to the greatest extent.
(2) The electromagnetic radiation released when the mobile phone is connected is the largest. For this reason, it is best to answer the phone one or two seconds after the mobile phone rings or between the two rings of the phone.
(3) The radiation produced by the screens of TVs, computers and other electrical appliances will cause dryness and dehydration of human skin, accelerate skin aging, and even cause skin cancer in severe cases. Therefore, you should promptly remove the above electrical appliances after using them. Wash your face.
(4) Eat more foods rich in vitamins A, C and protein such as carrots, bean sprouts, tomatoes, rape, kelp, cabbage, lean meat, animal liver, etc. to help regulate the electromagnetic field disorder of the human body. Strengthen the body's ability to resist electromagnetic radiation
In short, shielding is the key point. (The simple model is that inside the metal basket, it is a shielded area)
