Chemical resistance Resistant To Most Chemicals Radiation Protection Lead Glass Designed for X Ray Rooms and Nuclear Medicine Environments

Some radiology and nuclear medicine facilities operate in non‑standard environments: tropical climates, desert regions, high‑altitude, or high‑dose research facilities.

Jovvi Extreme Grade uses:

• Enhanced CeO₂ (1.5 wt% – 50% more than nuclear grade)

• Special edge sealant (silicon‑modified polyurethane, resists hydrolysis)

• Anti‑fog coating on both sides (for high‑humidity environments)

Scenario A: Tropical Hospital (Southeast Asia)

• Challenge: 90% humidity, monsoon season. Standard glass developed condensation between glass and frame.

• Jovvi solution: Extreme Grade with desiccant‑filled frame and breather valve.

• Result: No condensation after 2 years.

Scenario B: Desert Clinic (Middle East)

• Challenge: 45°C ambient, dust storms. Glass surface temperature reached 60°C. Thermal stress cracked previous glass.

• Jovvi solution: Extreme Grade with higher thermal shock tolerance (50°C differential) and dust‑sealed frame.

• Result: 3 years without failure.

Scenario C: Research Cyclotron Facility (High‑dose Area)

• Challenge: Glass located near 30 MeV proton beam (neutron activation concerns). Cumulative gamma dose 5× higher than clinical PET‑CT.

• Jovvi solution: Extreme Grade + quarterly inspection service. Additional neutron shielding recommended (boron‑loaded frame).

• Result: No browning after 18 months; still within ΔE < 2.0.

Jovvi Extreme Grade includes:

• Thermal cycling test report (–10°C to +60°C, 50 cycles, no failure)

• Humidity test (95% RH, 30 days, no edge degradation)

• UV exposure test (500 hours, no yellowing)

• High‑dose gamma test (10⁷ mGy, ΔE < 3.0)

Lead time: 45 working days (special glass composition).
