Chapter 1 Entering the World of Tungsten Alloy Shielding Cans
1.1 Concept of Tungsten Alloy Shielding Can
Tungsten alloy shielding containers are functional containers designed and manufactured specifically for containing and shielding radioactive materials, using tungsten-based high-density alloys as the main material in modern radiation protection engineering . They fully utilize the significantly higher bulk density of tungsten alloys compared to lead, iron, or concrete, as well as their superior attenuation capabilities for gamma rays, X-rays, and neutron fluxes, achieving highly efficient radiation shielding within a very limited space. Simultaneously, they possess sufficient structural strength, thermal stability, chemical inertness, and long-term containment reliability. Compared to traditional shielding methods, tungsten alloy shielding containers completely break the inherent contradiction of “better protection, larger volume, and heavier weight,” significantly reducing the overall volume and mass for the same level of protection, thereby improving the space utilization, operational flexibility, and personnel accessibility of the facility.
In practical applications, tungsten alloy shielding containers serve as both the first physical containment barrier for radioactive sources or radioactive waste and a core engineering barrier for radiation dose control. They are widely used around nuclear medicine imaging equipment, isotope production hot chambers, industrial X-ray inspection darkrooms, irradiation channels in research reactors, high-energy physics experimental terminals, and in the temporary storage and transfer of radioactive waste, becoming a key physical component for achieving the principles of “optimal protection” and “minimized dose.” As radiation applications evolve towards higher activity, compactness, and mobility, tungsten alloy shielding containers have gradually replaced traditional lead containers, lead glass containers, and heavy concrete containers, becoming the recognized representative of high-end, green, and long-life shielding solutions in the field of radiation protection today.
1.1.1 Definition of Tungsten Alloy Shielded Can
A tungsten alloy shielding container is strictly defined as a composite engineering container made of tungsten-nickel-iron, tungsten-nickel-copper, or tungsten-nickel-iron-copper high-density alloys with a tungsten content of not less than 90%, manufactured through near-net-shape forming sintering, forging, or precision machining processes, possessing both radioactive material containment and radiation shielding functions. Its design must simultaneously meet the mechanical and thermal requirements of the International Atomic Energy Agency for radioactive material transport containers, the type approval conditions of national nuclear safety regulatory authorities for storage and handling containers, and the most stringent surface dose rate limits for medical and industrial radiation protection.
