This tungsten alloy radiation protection container is made of high-purity tungsten nickel alloy (WNiFe) and is designed for the safe storage, transportation, and operation of radioactive materials (such as medical isotopes, industrial flaw detection sources, etc.). With the excellent radiation shielding performance (density ≥18 g/cm³) and structural stability of tungsten alloy, the container can effectively attenuate γ/X-rays, ensure the safety of operators and the environment, and meet the stringent protection needs of the nuclear industry, medical, and scientific research fields.
- High radiation attenuation.
- Easy to keep clean & sterilize.
- Non-Toxic material.
- Dimensionally stable up to 1000 *c.
- Hard & Durable (no need for steel or plastic coating).
Carrying and keeping radioactive pharmaceuticals: For radioactive pharmaceuticals such as 32P, 89Sr, and 90Y, tungsten alloy radiation containers are good options for their storage and transportation. These pharmaceuticals aid in the diagnosis and treatment of the different types of cancers. Because surgical and diagnostic procedures that are done on the patients and the medical personnel must be done safely, tungsten alloy containers are useful as they provide effective shielding from radioactive rays.
Keeping radioactive nuclides: As part of the surgical and diagnostic procedures that are done on the patients, cobalt 60, cesium 137, and iridium 192 are some of the radioactive nuclides that are used. These radioactive nuclides can be stored and transported in tungsten alloy shielding containers because tungsten alloys have high density and good radiation shielding.
