Component Specifications

Definition
The Primary Shield Wall is a critical structural component designed to attenuate ionizing radiation in industrial applications. It serves as the main barrier in radiation shielding structures, typically constructed with high-density materials to absorb and scatter radiation particles, protecting personnel, equipment, and the environment from harmful exposure. This component is engineered to meet specific radiation attenuation requirements while maintaining structural integrity under operational conditions.
Working Principle
Operates on the principle of radiation attenuation through absorption and scattering. High-density materials with appropriate atomic numbers interact with incoming radiation particles (gamma rays, neutrons, etc.), reducing their energy through photoelectric effect, Compton scattering, and pair production. The wall thickness and material composition are calculated based on required attenuation levels, radiation type, and energy spectrum.
Materials
Lead (Pb-99.9% purity), Concrete (high-density, 3.5-4.5 g/cm³), Tungsten alloys, Borated polyethylene for neutron shielding, Steel (for structural support)
Technical Parameters
  • Density ≥11.34 g/cm³ (lead equivalent)
  • Surface Finish Smooth, non-porous, corrosion-resistant coating
  • Thickness Range 50-300 mm (varies by material)
  • Radiation Attenuation ≥90% for specified energy range
  • Temperature Resistance -20°C to +80°C
  • Structural Load Capacity ≥500 kg/m²
Standards
ISO 4037, ISO 8529, DIN 25413, ASTM E665

Frequently Asked Questions

What is the typical lead equivalent thickness for a Primary Shield Wall?

Lead equivalent thickness typically ranges from 5-30 mm Pb depending on the radiation energy and required attenuation. For 150 keV gamma rays, 1.5 mm Pb provides approximately 90% attenuation.

How often should radiation shielding components be inspected?

Annual visual inspections and radiation surveys are recommended, with comprehensive testing every 3-5 years or after any structural modifications.

Can Primary Shield Walls be customized for different radiation types?

Yes, materials and configurations can be optimized for specific radiation types: lead for gamma rays, borated materials for neutrons, and layered composites for mixed radiation fields.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
