Nowadays, the application of radiation in medicine is very common. While ionizing radiation could be dangerous for human life depending on its energy. So, there are three principles for protection against the hazards of radiation. They are time, distance, and shield. Just stay as less time as possible around the radiation sources and stay as far as possible away from the radiation sources. While shield is the best way to protect patients, medical staff and researchers from the hazardous effects of radiation. There are various shields for medical applications. For example, gamma rays could easily penetrate through the human body. Therefore, high-density materials such as tungsten alloy shielding material are used for gamma ray protection. In a word, tungsten alloy shielding material is a promising lead-free radiation shielding material.
