Tungsten Alloy γ-ray Shielding Material

Tungsten alloy γ-ray shielding material is a new lead-free shielding material so that it is more suitable for medical applications than traditional lead shielding material.

In radiotherapy, gamma radiation is used to kill cancer cells by targeting the cancer cells with a beam of gamma radiation and then rotating the source of the beam. However, γ-rays are a kind of particles that have stronger penetrating power than alpha particles and beta particles. It has a certain harm to human body and also produces a certain amount of radiation pollution to the environment. So, different ways are used for protection against the hazards of radiation, one of which is shielding. Generally, lead is used as shielding material for protection against radiation, but lead is toxic. Therefore, nowadays, researchers are generally studying non-toxic tungsten polymers and high-density tungsten alloys for radiation protection.
