Lead bricks are commonly used as radiation shielding. Lead shielding refers to the use of lead as a form of radiation protection to shield people or objects from radiation so as to reduce the effective dose.
Types & Applications. Served shields are spiral-wound groups of small-gauge wire strands surrounding the insulation of the conductor(s). They are easy to unwind and terminate, but are prone to be relatively inductive because they are coiled around the cable. They are the most flexible of shielded cables, and are often used in audio applications.
