High Energy Tungsten Heavy Alloy Radiation Shielding For Medical / Nuclear Equipment
Tungsten alloy is ideal for shielding against X rays and gamma radiation. The very high density of tungsten shielding (more than 60% denser than lead) allows a reduction in the physical size of shielding components, without compromising their rigidity or the effectiveness of the shielding characteristics..
Applications include Collimators for the Medical Industry, Shielding Blocks, Oil Well Logging Tools and Instrumentation and Nuclear Equipment. Tungsten Heavy Alloy is an excellent material for use in Radiation shielding (high energy photonic). Grades HD180 and HD185 are most popularly used for this application. These alloys are excellent materials for shielding and collimation due to their combination of radiographic density, machinability, strength, and low toxicity. Tungsten Heavy Alloy offers a superior protection level to lead in an equivalent thickness and, unlike lead, resists deformation and can be accurately fastened.
Tungsten heavy alloy shielding is used in applications such as collimator, nuclear shielding, beam stop, PET syringe shield, vial shield, isotope container, FDG container, multi leaf collimator etc.
Tungsten Alloy Radiation Shielding Advantages:
Use not subject to NRC, EPA, or special OSHA regulations
High radiation absorption (superior to lead)
Low toxicity-safer than lead or depleted uranium: simplified life cycle
Easily machined into complex geometries
Hardness, strength, and ductility make for good durability
Good corrosion resistance
