Jovvi lead glass for nuclear medicine differs significantly from general radiology glass. While X-ray rooms require 1.8–2.5 mm Pb equivalent, PET/CT and SPECT involve higher-energy gamma photons (e.g., 511 keV from FDG, 140 keV from 99mTc). Jovvi addresses this with:
Increased lead equivalence – 3.5 mm to 5.0 mm Pb for nuclear medicine hot labs and camera rooms.
High-density formulation – up to 6.2 g/cm³, achieved with 65–70% lead oxide by weight.
Gamma-specific attenuation curve – tested at 140 keV, 364 keV, and 511 keV (not just diagnostic kVp ranges).
Optical clarity – >80% visible light transmission despite higher lead content; minimal yellow-brown tint via cerium oxide stabilization.
Non-activation guarantee – after extended exposure to high-energy photons, Jovvi glass does not become measurably radioactive (tested per NRC Reg Guide 8.30).
Each panel is 100% inspected for bubbles, striae, and lead distribution uniformity using digital radiography.
2. Application Scenarios – From CT to Hot Lab

Jovvi also supplies mobile shielding screens with casters for temporary use in high-dose nuclear medicine procedures (e.g., 131I therapy).
3. Production Assurance – Nuclear-Grade Quality Management
Jovvi maintains production guarantees specific to nuclear medicine applications:
Raw material certification – lead oxide free from uranium or thorium impurities (radiopurity verified by gamma spectroscopy).
Process validation – each melt batch includes a “witness coupon" tested at 511 keV using a Cs-137 or Na-22 source.
Documentation – every panel ships with:
Lead equivalence certificate (keV-specific, not just mm Pb equivalent at 100 kVp)
Light transmittance spectrum (400–700 nm)
Non-activation test summary (based on material composition)
Regulatory compliance – ISO 13485:2016, CE class I medical, FDA listed; meets NRC shielding design objectives for controlled areas (0.02 mSv/week for public).
Custom sizes – up to 2000 * 1200 mm single panel; larger walls achieved with staggered joints and over-lapped lead-lined frames.
Lead time – 30–35 days for nuclear-grade glass (extended due to radiopurity testing).
Warranty – 5 years against radiation-induced browning or lead equivalence degradation.
