ABOUT PRODUCT
Gamma radiation and X-rays are absorbed most effectively byhigh-density materials. AT&M high-density materials are a family oftungsten-based materials with densities 50% greater than that of lead.The high-density, good mechanical strength and excellent machinabilityof AT&M materials make them ideal for shielding applications. A varietyof sizes and shapes are available.
