Shielding: Protection from electromagnetic fields and radiation

In today's world, where technology and electronics play an increasingly important role in our daily lives, issues of safety and protection from electromagnetic fields and radiation are becoming increasingly relevant. One method of protecting against such fields is shielding—the process of placing a barrier between an object and a source to prevent the negative effects of electromagnetic fields and certain types of radiation.

Shielding is used in a variety of applications where there is a potential hazard to human health or an undesirable effect on the operation of electronic devices. In industrial environments where powerful sources of electromagnetic fields are present, shielding can be used to protect workers from the negative effects of these fields on their bodies. This is especially important in industries that manufacture and use high-power electronics, such as the radio frequency and electrical industries.

Another area of ​​application for shielding is medicine. In the diagnosis and treatment of various diseases, powerful medical devices that generate strong electromagnetic fields or radiation can be used. To prevent negative consequences for patients and medical personnel, special shielding materials and structures are used that create a barrier between the radiation source and the environment.

There are several shielding methods, including the use of special materials that have high electrical conductivity or magnetic permeability. These materials are capable of absorbing or reflecting electromagnetic fields and radiation, preventing their penetration into the protected space. In addition, facility designs can be specifically designed to reduce the effects of electromagnetic fields and radiation distortion.

Today, shielding has become increasingly complex and important as technology continues to advance and the use of electromagnetic fields and radiation becomes more widespread. Engineers and scientists continue to explore new shielding materials and methods to improve shielding effectiveness and minimize negative impacts on humans and the environment.

In conclusion, shielding plays an important role in providing safety and protection from exposure to electromagnetic fields and radiation. It has applications in a variety of fields including manufacturing, medicine and scientific research. The development of new technologies and materials is improving shielding methods and providing more effective protection against electromagnetic fields and radiation, reducing health risks and ensuring the reliability of electronic systems.

Shielding

Shielding is a method of protecting any equipment from the effects of electrical or other interference, such as electromagnetic fields or certain types of radiation. This method is used to prevent unwanted electromagnetic interference from entering equipment and preventing errors in the operation of electronic devices.

The most common example of shielding is the protective shielding of television cameras and radio equipment. To protect the moving camera in the viewfinder and lens from external electromagnetic interference, the entire camera unit is surrounded by a massive metal shield. Various types of screens are also used that are placed between the sound sensor input and data processing. Various screen examples:

1. Rubber-coated shielding cable reduces acoustic noise due to cable friction in different parts of the room. It is in many cinemas. 2. Frequency filters are mounted between microphones and other electronic devices to correct the audio frequency in the listening space to which they are directed. 3. Ultrasonic sensors are used to switch on-off signals. As the name suggests, these are active sensors that generate ultrasonic waves to detect objects. 4. Radio signal modulation. The signal is transmitted through the radio using frequencies. Overcompression is produced
