Tungsten alloy radiotherapy shield is the appropriate choice for the application in radiation shielding, that can be used in medical treatment. Tungsten alloy radiotherapy shield is preferablly used in multileaf collimator, collimator, linear accelerator and so on. Compared to common radiation shielding materials, such as lead, it provides outstanding characteristics.

The Advantages of Tungsten Alloy Radiotherapy Shield

The 3mm thickness of tungsten alloy shield can protect 95% of 150keV γ radiation. Tungsten alloy shield is perfect for high-spatial resolution, especially generated by radiological Imaging array detectors. Tungsten alloy shield possesses high degree of density, (60% higher than lead), lowers down the size of tungsten alloy ray shields, without impacting the radiation shielding capacity. Tungsten alloy shield embodies the capability of varied high-ray shielding.Comparing to tungsten alloy and lead, when they with the same performance of radiation blocking, the volume of tungsten alloy is 1/3 of lead. Tungsten alloy radiotherapy shield is also considered environmental protection material, as compared to lead, it is better to make use of tungsten alloy shield in radiotherapy treatment to cut down damage.

The Applications of Tungsten Alloy Radiotherapy Shield in

  • Collimator

  • Computed tomography

  • Linear accelerator

  • Multileaf collimator

  • X-ray energy absorptiometry
