Applications of Tungsten Alloy Shielding Cans in the Medical Field

Tungsten alloy shielding cans, owing to their high density, excellent radiation shielding performance, and mechanical stability, have notable applications in the medical field. Particularly in nuclear medicine, radiotherapy, and medical equipment manufacturing, these cans enhance the safety and reliability of medical procedures with their efficient radiation protection and compact design.

1. Storage and Transportation of Radioactive Isotopes in Nuclear Medicine

In nuclear medicine, radioactive isotopes are widely used for diagnosis and treatment, such as in positron emission tomography (PET) or single-photon emission computed tomography (SPECT). These isotopes emit high-energy gamma rays, posing potential radiation risks to medical staff and patients. Tungsten alloy shielding cans, with their high density, effectively shield gamma and X-rays, reducing the risk of radiation leakage. Compared to traditional lead shielding materials, tungsten alloy achieves equivalent shielding with a thinner profile, facilitating transportation and operation in hospital settings.

2. Radiation Protection in Radiotherapy

In radiotherapy, tungsten alloy shielding cans protect patients and medical personnel from radiation hazards generated by treatment equipment. For instance, in devices like the Gamma Knife or linear accelerators, tungsten alloy is used to manufacture shielding containers or components that confine radiation to the targeted treatment area, minimizing damage to surrounding healthy tissues. The high density of tungsten alloy enables powerful shielding in a smaller volume, which is crucial for equipment requiring precise radiation dose control. Additionally, its mechanical strength and heat resistance allow it to withstand the high heat and mechanical stress during equipment operation, extending the device's service life.

3. Dispensing and Injection of Radioactive Drugs

In nuclear medicine diagnostics, the dispensing and injection of radioactive drugs require high levels of radiation protection. Tungsten alloy shielding cans serve as dispensing containers for radioactive drugs, safeguarding medical staff during handling. The high density ensures strong shielding even with high-dose radioactive drugs, while its smooth surface finish and corrosion resistance facilitate cleaning and disinfection, meeting the hygiene standards of medical environments.
