Shielding is a method used to protect sensitive electronic components from external electromagnetic interference (EMI). This interference can disrupt the normal operation of devices, leading to malfunctions or data loss. Shielding materials, such as metals or conductive coatings, are often employed to create a barrier that absorbs or reflects unwanted signals. In addition to electronics, shielding is also important in other fields, such as nuclear physics, where it protects against harmful radiation. In this context, materials like lead or concrete are used to block radiation, ensuring safety for workers and the environment. Effective shielding is crucial for maintaining the integrity and safety of various systems.
