Q1: How should the dimensions of a sliding lead door be determined?
Q1: How should the dimensions of a sliding lead door be determined?
A: To ensure reliable radiation protection, the door dimensions must exceed the clear wall opening to provide an effective overlap.
Standard Specifications: Typically, the door height should be 50mm higher than the opening, and the width should be 200mm wider (100mm overlap on each side).
Enhanced Requirements: Depending on project sensitivity, some specifications require a height overlap of 100mm and a width overlap of 400mm (200mm on each side).
Technical Purpose: This overlap is designed to completely cover the wall opening, eliminating any "line-of-sight" gaps and effectively preventing radiation leakage.
Q2: How does a swing lead door prevent radiation leakage at the gaps?
Q2: How does a swing lead door prevent radiation leakage at the gaps?
A: The most vulnerable area for radiation leakage is the gap between the door leaf and the door frame. To solve this, HESITE utilizes an Integrated Frame-and-Leaf System.
By engineering the door and frame as a unified structural entity, we ensure a precision-fitted overlap. This integrated design minimizes structural tolerances and eliminates gaps at the hinges and meeting edges, thereby preventing any accidental radiation leakage and ensuring the highest level of safety.
