Tungsten alloy syringe shield applied for PET is made of high density tungsten alloy and lead glass. After special processing, such a syringe shield has a good radiation shielding effect on short-lived radionuclides such as 18F, 11C, etc, to provide good external radiation protection for nuclear medicine workers. PET is an abbreviation of Positron Emission Computed Tomography in English, a relatively advanced clinical examination imaging technology in the field of nuclear medicine.

Tungsten alloy syringe shield is mainly designed for the injection of 18F-FDG and other PET imaging drugs, to protect the staff from external radiation on the upper limbs and hands during working, as well as the external radiation during transportation.

Tungsten alloy radiation source container is the best radiation shielding container in nuclear medicine as tungsten alloy - the new kind of radiation shielding material - has the characteristics of high density (17.0-18.5 g/cm3), good machinability, good mechanical properties, high modulus of elasticity, high absorption capacity against X-ray and γ-ray. Also, unlike toxic lead container, tungsten alloy container is harmless to human health and environment.

Tungsten alloy shielding container is the best choice for radiation shielding applications in medical field. Compared to traditional radiation shielding materials, such as lead, tungsten alloy provides more excellent properties. For example, due to its high density, tungsten-based alloy shielding container can provide the same radiation absorption as lead using 1/3 less material.

Tungsten alloy radiation shielding door is the best choice for applications of CT room as tungsten alloy is a new type of radiation shielding material with the advantages of high density, high strength, easy cutting, good corrosion resistance, good thermal conductivity, good radiation absorption performance, and small thermal expansion coefficient.

Automatic tungsten alloy radiation shielding door is more and more popular as it is one of the effective measures to solve medical radiation pollution. There is radiation in CT room, radiation oncology room, etc. Therefore, in addition to the installation of radiation shielding parts in the diagnostic equipment in these rooms, a fully automatic tungsten alloy radiation shielding door is necessary, to protect the medical staff and patients outside the door from radiation pollution.

Why do we need tungsten medical radiation shielding? You know, there are more and more radiation equipment appearing in our life with the development of medical technology. And these pieces of medical equipment have a significant influence on our lives. While the radiation therapy equipment such as linear accelerators, cobalt 60 and X-ray detectors work by emitting radiation sources. So it is important to protect people from the harm of radiation sources such as X-rays, gamma rays, alpha particles, and beta particles, etc.

Preparation of defective tungsten oxide nanopowder is widely studied as defective tungsten oxide nano powder has wide applications in solar power generation, seawater desalination, and sewage treatment. Defective tungsten oxide nanopowder is a kind of photothermal conversion material, which can convert sunlight into heat energy to heat the base liquid, and realize the photothermal conversion. Specifically, the application of tungsten oxide nanoparticles is to convert water into steam on a large scale under the radiation of the sun or solar simulator to achieve solar power generation, seawater desalination, or sewage treatment. Well, do you know how to prepare defective tungsten oxide nanoparticles?

WO3, an n-type semiconductor, is an excellent gas-sensing material and has good sensitivity to toxic gases such as NO2. According to the experts, in recent years, with the rapid development of economy and industry, toxic gases such as NO2 have caused serious environmental pollution problems, such as acid rain, photochemical smog, etc. Due to their toxicity and destructiveness, the detection of NO2 and other toxic gases has paid much attention.

WO3 nanoparticles are often made into gas sensor for detecting various toxic gases. For example, WO3 nano particles have high sensitivity and selectivity to trimethylamine and high sensitivity to acetic acid, acetaldehyde, acetone, and ethanol gas.
