Medical tungsten alloy radiation shield refers to a shielding part made of high-density tungsten-based alloy with the composition of W-Ni-Fe, W-Ni-Cu or W-Ni-Cu-Fe. During the generation of X-ray radiation in medical treatment, the tungsten alloy radiation shield is an appropriate radiation dose-reducing measure to minimize risk to the patient and the medical team.

Yellow tungsten oxide titanium dioxide composite catalyst is a new type of non-toxic photocatalyst of high efficiency, which can be prepared into powder coating or other styles of green materials, for applications in decontamination and purification of various environments. Well, how to prepare tungsten oxide titanium dioxide composite catalyst?

Tungsten alloy isotope container is a specially designed shielded transport container for radioactive sources. Also, such a container can also serve as a storage or exposure container for the radioactive sources. In nuclear medicine, it is necessary to store the radioactive sources safely, so vials of radiopharmaceuticals are held in tungsten alloy radiation shielding - tungsten alloy isotope container while the dose is drawn up into a syringe ready for treatment.

Compared with the pure yellow tungsten oxide film (WO3 film), the nanocrystalline yellow tungsten oxide film (nanocrystalline WO3 composite film) has a significantly enhanced electrochromic optical modulation amplitude and a faster response time. And its reversibility and coloring efficiency are also improved at the same time.
