Shielding structural design parameters serve as the critical bridge translating the theoretical shielding capability of tungsten alloy material into practical shielding effectiveness in tungsten alloy shielding containers, primarily involving wall thickness distribution, cavity geometry, labyrinth and sealing surface design, functional aperture treatment, gradient layer arrangement, and overall rigidity plus deformation resistance.
Wall thickness distribution uniformity and minimum thickness determine attenuation along the weakest path, with non-uniform or locally thinned regions becoming preferential leakage channels. Cavity geometry influences scattered photon re-absorption efficiency; cylindrical or spherical inner cavities extend average ray path length, whereas sharp corners or flat cavities tend to create scattering accumulation at corners. Labyrinth and sealing surface design directly affect shielding continuity at joints; multi-step hard-metal fitting combined with elastic sealing rings effectively blocks through-gap leakage.
Functional apertures (viewing windows, detection ports, waste liquid outlets) can become directional weak zones if improperly handled and require nested tungsten alloy sleeves, stepped shielding, or closable tungsten covers to achieve attenuation equivalent to the main body. Gradient layer arrangement provides mechanism complementation in broad-spectrum shielding, with high-tungsten inner layers handling primary absorption, middle absorber inserts addressing thermal neutrons, and outer corrosion-resistant coatings simultaneously serving decontamination and secondary electron suppression. Overall rigidity and deformation resistance ensure that minimum wall thickness and sealing gaps remain unchanged under transport, drop, thermal cycling, or long-term self-weight.
Rational structural design enables tungsten alloy shielding containers to approach the material’s theoretical shielding limit under complex source terms and harsh environments, delivering reliable dose control and containment safety in nuclear medicine hot cells, isotope production, and industrial irradiation facilities.
