Radio broadcasting, television and microwave technologies are rapidly gaining popularity. The power of radio frequency equipment has doubled so that the intensity of nearby electromagnetic radiation reaches a level that directly threatens human health.

The means of protection of electromagnetic radiation is generally to place electromagnetic shielding devices around the radio frequency equipment or the protection object so that the electromagnetic radiation intensity within the protection range falls within the allowable range. Electromagnetic shielding devices are the main shield, shielding room, shielding clothing, helmet and goggles mask, shielding different objects, using different devices. In addition, comprehensive prevention and control measures should be taken, such as rationalizing the layout of electromagnetic pollution sources away from populated residential areas, improving electromagnetic equipment so as to reduce the electromagnetic radiation to the environment, enhancing the automation and remote control of electromagnetic equipment to reduce the workload of staff Exposure to high-intensity electromagnetic radiation opportunities.
