The easiest way to prevent electromagnetic radiation is to stick an aluminum plate on the wall and then stick a steel plate (not a stainless steel plate). The board needs to be grounded. It's just that you should consider these expenses. If you can't afford to put aluminum plates at the same time, put a layer of steel plates. Or it can be coated with some radiation-proof materials. Radiation protection coating is a high-tech patented product based on the compatibility of stealth coating technology of fighter and ferrite absorbing materials, which is suitable for civil electromagnetic radiation protection. It is an environmentally friendly and electromagnetic wave-absorbing waterborne special coating, which can purify and establish a healthy electromagnetic wave space and protect people and equipment from electromagnetic wave damage and interference. Radiation protection coating is an application of radiation protection method strongly recommended by environmental protection department, and it is an international technology to control space electromagnetic wave pollution. Any unit or individual that produces electromagnetic radiation pollution should strive to reduce its electromagnetic radiation pollution level on the principle of "as low as possible".
The electromagnetic radiation detector can detect the electromagnetic radiation at home and in the workplace. Hold the electromagnetic radiation detector in your hand, aim the "test area" at the object to be measured, and slowly approach the object until it actually touches the object. The closer to the measured object, the stronger the electromagnetic field or electric field and the faster the reporting frequency. In the measurement, try to change the angle and position of the measured instrument, and you can get a larger reading. Long-term exposure to electromagnetic radiation will also affect and destroy the original bioelectric current and magnetic field of human body, making the original electromagnetic field in human body abnormal. Old people, children and pregnant women are sensitive to electromagnetic radiation, and their reactions will be particularly strong. # # # Recommended FD-30 13B intelligent gamma radiometer. Electromagnetic radiation can be classified by frequency, from low frequency to high frequency, including radio waves, microwaves, infrared rays, visible light, ultraviolet rays, X rays and gamma rays. The wavelength of electromagnetic radiation that human eyes can receive is about 380 to 780 nanometers, which is called visible light. Any object whose temperature is above zero will emit electromagnetic radiation.
