Market Background

With the rapid development of industrial non-destructive testing (NDT), medical imaging, and laboratory research, the use of X-ray and gamma-ray equipment has increased significantly worldwide. While these technologies improve inspection accuracy and operational efficiency, they also introduce strict requirements for ionizing radiation protection. Governments and regulatory bodies continue to tighten safety standards, pushing manufacturers, hospitals, and testing centers to invest in reliable and compliant radiation shielding solutions. Among various shielding materials, lead bricks remain the most effective and flexible option due to their high density and proven attenuation performance.

Customer & Application Scenario

A regional industrial NDT service provider required a modular radiation shielding system for an X-ray flaw detection room used in weld inspection and material testing. The facility faced multiple challenges: limited space, frequent changes in inspection layout, and strict dose limits for operators and surrounding personnel. Traditional concrete shielding was inflexible and costly to modify, while steel shielding increased construction complexity. The customer needed a solution that could be quickly installed, adjusted, and redeployed without compromising radiation safety.

Our Solution

Chengxin Radiation Protection Co., Ltd. supplied interlocking lead bricks cast from high-purity lead and lead-antimony alloy. The rectangular brick design with an interlocking structure ensured tight assembly, minimizing radiation leakage at joints while maintaining excellent mechanical stability.

Based on the customer’s X-ray machine voltage, working hours, distance from the radiation source, and environmental factors, our engineering team calculated the optimal shielding thickness and wall configuration. The modular lead brick system allowed the customer to build a fully enclosed shielding wall and later modify it as inspection requirements changed. This approach significantly reduced installation time and future reconstruction costs while ensuring compliance with national radiation protection standards.
