Lead Sheet Installation Guide  

Q: How do we ensure no radiation leakage at the joints?  

A: The most critical step is overlapping. Adjacent lead sheets must overlap by at least 15-20mm. If the lead sheets are thin (under 1.5mm), we recommend increasing the overlap to 30mm or using a double-layer staggered joint layout to ensure 100% shielding integrity.

Q: How to fix heavy lead sheets to the wall without sagging?  

A: Due to lead's weight and softness, it must be fixed to a solid substrate (like plywood or calcium silicate board).。Mechanical Fixing: Use wide-head screws every 200-300mm.Lead Caps: Every screw head must be covered with a small lead disc or lead tape of the same thickness to prevent "pinhole" leakage.

Q: What is the proper sequence for ceiling shielding?  

A: For ceilings, lead sheets are usually sandwiched. First, install a heavy-duty steel channel frame, then fix the lead sheets to a carrier board (like marine plywood). Never leave the lead sheet exposed; always finish with a layer of fireproof gypsum board for aesthetic and safety purposes.

"Note: All shielding construction should be verified by a local qualified physicist or radiation safety officer (RSO) after completion."
