Gamma rays present significant health risks by damaging surrounding cells. Shielding materials interact with gamma radiation, attenuating its intensity based on factors such as atomic number, density, and thickness. Effective radiation shielding is imperative to safeguard human health and the environment.

The choice of shielding material hinges on factors like cost, weight, durability, and toxicity. Materials with high density and high atomic numbers typically offer superior attenuation capabilities.

The adverse health and environmental impacts of lead create a need for alternative shielding materials. Tungsten emerges as a great option due to its non-toxic nature, high density, and superior shielding properties, serving as a promising substitute for lead in various applications.

The Benefits of Tungsten Shielding are:

• High radiation attenuation
• Easy to keep clean & sterilize
• Non-Toxic material
• Dimensionally stable up to 1000°c
• Hard & Durable (no need for steel or plastic coating)

T&D tungsten alloys find versatile applications across various industries. They are utilized in radioactive source containers, gamma radiography, shields, and source holders for oil-well, logging, and industrial instrumentation. High-density alloys serve crucial roles as collimators and radiation shielding in cancer therapy, in addition to syringe protection for radioactive injections.

When precise control over radiation direction is essential, tungsten alloys offer the necessary control. Our high-density alloys consistently deliver optimal performance, even under high-heat conditions.

In comparison to conventional radiation shielding materials, tungsten alloys offer exceptional value. A high-density alloy can match the energy absorption of lead while requiring only one-third of the material! Moreover, by using tungsten alloys, you can streamline administrative processes and reduce costs as special licensing is unnecessary, unlike with lead.

NEUTRON SHIELDING

Neutron Shielding involves a polyethylene container with dispersed low atomic element materials to effectively moderate and thermalize incident neutrons. Surrounding the container is Bismuth shielding to reduce gamma radiation doses resulting from neutron capture interactions. This combination efficiently attenuates various levels of Alpha particles and their high-intensity by-products.

Our Tungsten metals possess the necessary properties for radiation shielding in both therapeutic and diagnostic settings. They find widespread use in applications such as collimators, syringe and vial shields, and radioactive source containers.

T&D is actively involved in Nuclear Medicine applications, where our tungsten base materials play a vital role in radiation shielding for drug storage and delivery, containment vessels, shielding and directional focus apparatus. Notably, they offer effective protection without the health or environmental risks associated with lead.

The nominal tungsten content ranges from 90% to 97% and densities between 17 and 19 g/cm3.
