Shielding techniques are methods used to protect individuals or sensitive equipment from harmful electromagnetic fields or radiation. These techniques can involve physical barriers, such as walls made of lead or copper, which absorb or deflect radiation. Additionally, specialized materials like RF shielding paint can be applied to surfaces to reduce electromagnetic interference. In various industries, shielding techniques are crucial for ensuring safety and compliance with regulations. For example, in the medical field, X-ray rooms are designed with shielding to protect patients and staff from radiation exposure. Similarly, electronic devices often incorporate shielding to prevent interference from external signals, ensuring optimal performance.
