When evaluating lead glass suppliers for nuclear medicine and radiology, demand documented evidence for:
Measured lead equivalence (not theoretical) – with test method and uncertainty
Bubble specification – accept only <0.5 bubbles >0.5 mm per 100 cm²
Browning resistance – CeO₂ content and radiation stability test (500+ hours)
Traceability – laser‑etched serial number linking to batch test records
Warranty – minimum 5 years against discoloration, cracking, attenuation loss
Jovvi exceeds all five requirements.

100% X‑ray inspection – every panel scanned for internal defects
Measured attenuation – not calculated (IEC 61331‑2 compliant)
Nuclear grade CeO₂ – prevents browning (test certificate included)
Edge chamfer – prevents chipping during installation
Stress‑relieved annealing – <20 nm/cm residual stress
Flatness guaranteed – <0.1% of diagonal
Laser‑etched serial number – full traceability
ISO 13485:2016 certified – medical device quality management
5‑year warranty – covers discoloration, cracking, attenuation loss
Post‑installation support – re‑certification and maintenance services
Phase 1 – Planning (4–6 weeks before order)
Determine modality (X‑ray, CT, SPECT, PET‑CT, or mixed)
Measure workload (patients/week or mAs/week)
Calculate required Pb equivalent (or use Jovvi free design service)
Confirm wall/frame can support glass weight
Obtain budget approval (include TCO, not just initial price)
Phase 2 – Ordering (3–6 weeks before delivery)
Select Jovvi product from matrix above
Provide exact rough opening dimensions (±2 mm)
Specify any custom features (holes, rounded corners, anti‑reflection coating)
Request nuclear supplement if SPECT/PET‑CT
Confirm lead time and shipping method
Phase 3 – Delivery & Installation
Inspect crate for damage before opening
Verify panel dimensions against shop drawing
Check for bubbles, scratches, orientation arrow
Follow Jovvi installation guide (torque specs, gasket, lead tape)
Perform post‑installation radiation leakage test
Phase 4 – Ongoing (annual)
Visual inspection for new bubbles, edge chips, discoloration
Re‑check torque on clamping bolts
Inspect lead tape perimeter
Conduct radiation survey (compare to baseline)
Record all results in shielding log
