Key Precautions for Lead Shielding Glass in X-ray Rooms

1. Handling & Transportation

Lead glass is heavy, brittle and sensitive to local stress.

• Always carry it with soft protective foam, avoid direct hard contact on the glass surface and edges. Edge chipping is the most common defect that may spread into cracks later.
• Do not lift the glass by one corner alone; support the whole panel evenly.
• Keep vertical storage during transit, never stack flat without thick cushion layers. Do not place heavy goods on top.

2. Installation Notes

• Use customized lead frame / shielding frame matching the declared lead equivalent. Gaps between glass and frame must be sealed with lead strips to prevent radiation leakage. A tiny gap can become a radiation weak point.
• Leave proper expansion gap; do not clamp the glass too tight. Thermal expansion stress will crack the panel.
• Avoid direct nail, drill or cutting on finished lead glass on site. Any on-site cutting will destroy the protective layer and change local lead equivalent. Confirm size before ordering.

3. Daily Cleaning & Surface Protection

• Clean only with soft microfiber cloth + neutral mild detergent and clean water.
• Forbidden: abrasive powder, steel wool, acidic / alkaline cleaner, acetone or strong solvent. They will corrode the surface and cause fogging, which reduces visibility and gradually damages the glass structure.
• Do not stick hard labels, adhesive tapes directly on the viewing side. Residue is hard to remove and leaves permanent marks.

4. Radiation Performance & Environment Limits

• Confirm the lead equivalent (e.g. 0.5mmpb, 1.0mmpb, 2.0mmpb) matches your equipment voltage. One lead glass cannot fit all X-ray energy levels.
• Long-term continuous high temperature, humid, salty or corrosive environment will accelerate surface aging. Keep room ventilation stable.
• Lead glass is NOT scratch-resistant. Scratches do not immediately reduce shielding ability, but deep scratches can grow into cracks under vibration.

5. Regular Inspection & Replacement Rule

• Visual check every month: look for cracks, bubbles, surface fogging, edge damage.
• Annual radiation leakage test is recommended together with the whole shielding room survey.
• Once cracks appear, stop using immediately. Cracked lead glass loses shielding integrity and cannot be repaired. Replacement is required.

6. Safety Reminder for Broken Lead Glass

Broken pieces contain lead. Collect fragments carefully, wear gloves, avoid skin long-time contact. Dispose as hazardous waste following local environmental regulations. Do not mix with normal construction garbage.

Final Tip: Lead glass is a shielding consumable with a service life. Good installation + gentle maintenance keeps its shielding effect stable for years.
