Does lead glass protect from radiation? Yes, this type of glass is important to provide safety from radiation. Lead glass and other forms of specialty glass are now regarded as critical materials for radiation shielding. Lead-containing glasses absorb gamma, x-ray, and neutron radiation significantly, in addition to having adjustable mechanical, chemical, and optical characteristics. Does glass show up on X-ray? Radio-opaque materials, such as glass or metal, are typically visible. Other less thick materials, such as wood, are not easily recognised by X-rays.
