Workers are exposed to radiation in the process of radiopharmaceuticals, packaging, and injection. Tungsten alloy syringe shield, made of tungsten alloy, is medical tungsten alloy shield used for medical injection of radioactive drugs. Its density up to 16.5-19.0g / cm3, have a good shielding effects on radioactive particles.

 

Tungsten alloy syringe shield is commonly used in medical devices as isotope tracer methods to monitor the efficacy of drugs. Through releasing characteristic rays by radioactive isotopes, nuclear detectors can be used to track its position in vivo or in vitro, the number and its transformation. the stability of isotopes, although not releasing radiation, it can determine by using quality analysis equipment like mass spectrometry, gas chromatography and nuclear magnetic resonance that using quality difference with the corresponding isotope.

 

 

If the radioactive material exposure or into the human body, it will make the cells lesions and serious harm to human life. Radiation of radioactive materials must be controlled at a sufficiently low level of radiation to avoid harmful ionizing radiation, which would not lead to cancer such as lung and skin cancer.

 

Selecting tungsten heavy alloy shield as shielding material is because tungsten alloys have excellent ability to absorb radiation. It also has high density (twice as high as lead) and good corrosion resistance. Tungsten alloy shielded needle in the use of radioactive material can protect the body from harm.
