Core Sheet Weight / Area Density
The below values are approximate core material weight per square metre. Final apron weight may vary depending on apron size, outer fabric, stitching, binding, hook and loop closure, buckles, pockets, and accessories.
NoPb®-BL Sheet / Construction
Approx. Core Weight
0.175 mmPb single sheet

The broad beam report lists the 0.175 mmPb material at 2.13 kg/m², the 0.35 mmPb doubled construction at 4.29 kg/m², and the 0.25 mmPb material at 3.02 kg/m². The separate HPNW broad beam report lists the 0.50 mmPb two-layer construction at 6.0 kg/m².
Modified broad beam geometry
NoPb®-BL Broad Beam Test Performance
NoPb®-BL has been tested under modified Broad Beam Geometry, which is useful for evaluating lead-free X-ray protective clothing materials. The report defines the attenuation ratio in modified broad beam geometry and states that lead equivalent values are obtained by fitting attenuation curves against known lead foils.
NoPb®-BL has been tested under modified Broad Beam Geometry, which is useful for evaluating lead-free X-ray protective clothing materials. The report defines the attenuation ratio in modified broad beam geometry and states that lead equivalent values are obtained by fitting attenuation curves against known lead foils.
The 0.50 mmPb two-layer NoPb®-BL construction was tested from 60 kV to 130 kV, with broad beam attenuation from 99.7% at 60 kV to 94.1% at 130 kV.

How NoPb®-BL Is Used in IndoSurgicals Lead-Free Aprons
01
1. Frontal Protection Lead-Free Apron
In a frontal protection lead-free apron, the radiation protection core is used on the front side of the apron. This design is suitable for users who mainly face the radiation source during medical procedures.

2. Full-Overlap Full Protection Lead-Free Apron
In a full-overlap full protection lead-free apron, front protection is achieved when both front panels overlap each other. The back panel is always made with one 0.25 mmPb sheet.

0.25 mmPb, approx. 3.00–3.02 kg/m²
0.50 mmPb
03
3. Partial-Overlap Full Protection Lead-Free Apron
In the Partial-Overlap Full Protection Lead-Free Apron, both front panels are made with the full claimed lead equivalent protection. This design provides full front-side protection on each panel, while the overlapped front portion provides additional shielding because both protective panels come together in the overlap area.
Claimed Protection Level
Each Front Panel
Back Panel
Overlapped Front Area
0.35 mmPb
0.35 mmPb, approx. 4.29 kg/m² per panel
0.25 mmPb, approx. 3.00–3.02 kg/m²
Approx. 0.70 mmPb
0.50 mmPb
0.50 mmPb, approx. 6.00 kg/m² per panel
0.25 mmPb, approx. 3.00–3.02 kg/m²
Approx. 1.00 mmPb
In 0.35 mmPb partial-overlap aprons, each front panel is made with 0.35 mmPb lead equivalent protection. Therefore, wherever both front panels overlap, the combined protection becomes approximately 0.70 mmPb lead equivalent.
In 0.50 mmPb partial-overlap aprons, each front panel is made with 0.50 mmPb lead equivalent protection. Therefore, wherever both front panels overlap, the combined protection becomes approximately 1.00 mmPb lead equivalent.
The back panel is always 0.25 mmPb lead equivalent in both 0.35 mmPb and 0.50 mmPb partial-overlap full protection apron designs.
