Jovvi Lead Glass for X-ray, CT, SPECT, PET/CT & Nuclear Medicine – Version 1 (Comprehensive Overview)
1. Quality – Beyond Diagnostic X-Ray: Gamma Attenuation & Optical Performance

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
Facility Area Typical Pb Eq. Key Requirement
General CT room 2.2–2.5 mm Wide viewing area
SPECT camera room 3.0–3.5 mm 140–364 keV shielding
PET/CT control room 3.5–4.0 mm 511 keV attenuation
Hot lab (radiodispensing) 4.5–5.0 mm High dose rate >1 mSv/h
Radioisotope injection room 3.5 mm Patient visibility during infusion
Nuclear medicine waiting area (shielded partition) 3.0 mm Decorative/safety dual use

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.
