0.2m 0.3m to 2.4m 1.2m Radiation Protection Lead Glass Featuring High Impact

Quality is not subjective when it comes to radiation shielding. Jovvi lead glass is designed, tested, and certified to meet or exceed the following standards across all modalities (X‑ray, CT, SPECT, PET‑CT).

Different imaging modalities fall under different regulatory frameworks. Jovvi provides modality‑specific compliance packs.

• Required documentation: Lead equivalence certificate (IEC 61331‑2), visible light transmittance report

• Acceptance test: Radiation leakage around glass <0.05 mR/hr at 10 cm (typical US NRC or equivalent local authority)

• Jovvi deliverable: Standard compliance pack (included with every panel)

• Required documentation:

  • 140 keV attenuation measurement (⁹⁹ᵐTc)

  • Uniformity grid scan (no local weak spots)

  • CeO₂ certification for browning resistance

• Acceptance test: Annual leakage survey; glass must show <10% increase in transmission after 5 years (indicates no browning)

• Jovvi deliverable: Nuclear medicine supplement + radiation stability certificate

• Required documentation (most stringent):

  • 511 keV attenuation measurement (²²Na source)

  • Composite window layer‑by‑layer test report

  • Structural engineering sign‑off (due to weight >100 kg/m²)

• Acceptance test: Baseline leakage measured at 511 keV; repeat every 2 years

• Jovvi deliverable: PET‑CT compliance pack (extra cost) including 511 keV data and composite window design drawing

• Required documentation: Typically none specific, but good practice to have 140 keV test for ⁹⁹ᵐTc preparation areas

• Jovvi deliverable: Mini compliance certificate (abbreviated)

Jovvi maintains the following certifications, audited annually by notified bodies:

Additional regional compliance:

• China: NMPA (formerly CFDA) registration available for Type B lead glass (up to 3.0 mm Pb)

• Saudi Arabia: SFDA listing (medical device class I)

• Brazil: ANVISA registration (requires import certificate – Jovvi provides technical dossier)

• Japan: PMDA notification (Class I medical device – submitted by local importer)

For each shipment, Jovvi includes a regulatory dossier containing:

1. Certificate of Conformance (signed by quality manager) – lists panel serial number, Pb equivalent, dimensions

2. Lead equivalence test report – measured according to IEC 61331‑2 with stated uncertainty (±0.05 mm Pb)

3. Optical quality certificate – visible transmittance, distortion, bubble count

4. Material safety data sheet (MSDS) for lead glass (handling, disposal, recycling)

5. Installation certificate template – for hospital’s radiation safety officer to complete after installation

6. Suggested annual inspection log sheet

For nuclear medicine (SPECT/PET‑CT), the following are added:

• 140 keV attenuation report (if ordered)

• 511 keV attenuation report (PET‑CT only)

• Cerium oxide content certificate (evidence of browning resistance)

• Radiation stability test report (500 h gamma exposure)

A: In the EU and US, lead glass permanently installed into a shielded room is considered an accessory to a medical device (the X‑ray or gamma camera). It requires CE marking or FDA listing for its intended use. Jovvi provides both.

A: Jovvi certifies the glass panel itself. The installed system (frame, lead tape, wall shielding) is the responsibility of the installer. Jovvi provides installation specifications that, if followed, yield a compliant system.

A: No universal rule, but good practice:

• X‑ray/CT: every 5–10 years (or after any physical impact)

• SPECT: every 5 years (check for browning)

• PET‑CT: every 3 years (511 keV is more penetrating; also check for delamination in composite windows)

Jovvi can perform these re‑tests at discounted rates for original buyers.

A: The NRC does not directly certify lead glass, but NRC Regulatory Guide 8.13 (instruction concerning prenatal radiation exposure) references shielding design. Jovvi’s 140 keV and 511 keV attenuation data satisfy NRC‑recognized design methods (NCRP 151).
