NoPb®-SL Lead-Free Super Lightweight Radiation Protection Core Material

NoPb®-SL Lead-Free Super Lightweight Radiation Protection Core Material is a lightweight lead-free shielding material used in IndoSurgicals lead-free aprons and X-ray protection garments. It is designed to provide dependable radiation protection while reducing apron weight for healthcare professionals working in hospitals, radiology departments, diagnostic centers, cath labs, C-arm procedures, urology departments, dental clinics, veterinary clinics, nuclear medicine departments, and interventional procedure rooms.

NoPb®-SL is made using lead-free attenuation powders bonded inside a flexible POE polymer matrix. This material is suitable for users who need a lighter radiation protection apron for long working hours, without using traditional lead-based core material.

NoPb®-SL can be used for manufacturing lead-free radiation protection aprons, frontal protection aprons, full protection aprons, thyroid shields, gonad shields, dental aprons, patient protection shields, and other medical radiation protection products.

How NoPb®-SL Is Used in IndoSurgicals Lead-Free Aprons

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.

Claimed Protection Level	Core Sheet Construction	Approx. Core Weight
0.35 mmPb	2 sheets of 0.175 mmPb	3.90 kg/m²
0.50 mmPb	2 sheets of 0.25 mmPb	5.20 kg/m²

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.

Protection Level	Front Panel 1	Front Panel 2	Back Panel	Front Overlapped Area
0.35 mmPb	0.175 mmPb, 1.95 kg/m²	0.175 mmPb, 1.95 kg/m²	0.25 mmPb, 2.60 kg/m²	0.35 mmPb
0.50 mmPb	0.25 mmPb, 2.60 kg/m²	0.25 mmPb, 2.60 kg/m²	0.25 mmPb, 2.60 kg/m²	0.50 mmPb

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, 3.90 kg/m² per panel	0.25 mmPb, 2.60 kg/m²	Approx. 0.70 mmPb
0.50 mmPb	0.50 mmPb, 5.20 kg/m² per panel	0.25 mmPb, 2.60 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.
