Lead Lined X-Ray Shielding Doors
Precise protection: ≥2mm lead equivalent (customizable to 6mmPb), professional shielding of scattered X-rays, leakage rate <0.1%.
Silent operation: Brushless motor drive (noise ≤45dB), smooth opening and closing without interfering with the diagnosis and treatment environment.
Intelligent safety: Infrared + pressure strip double anti-pinch, manual unlocking during power outage, support door machine joint control.
Durable and easy to clean: 304 stainless steel/antibacterial coating surface, corrosion-resistant and wear-resistant, suitable for high-frequency use in hospital CT/DR rooms.
Space saving: Flexible design of sliding/opening to adapt to narrow passages.
X-ray lead shielding door is a radiation protection device that uses high-purity lead plate as the core shielding layer, combined with an intelligent drive system and multiple safety mechanisms. It is designed for medical radiology (CT/DR/DSA), industrial flaw detection, nuclear technology laboratories and other scenarios to ensure that the radiation dose is strictly controlled within the GBZ 130-2020 standard limit (leakage rate <0.25μSv/h), while ensuring efficient and safe passage of personnel.
Core technology and parameters
Shielding performance
Lead equivalent: basic configuration ≥2mmPb (customized range 1-8mmPb), X-ray shielding efficiency ≥99.95% for tube voltage ≤150kV
Anti-leakage design: the door gap adopts a three-order maze structure + lead-coated rubber sealing strip (compression rebound rate > 90%), and the edge leakage dose attenuation is 98%
Material structure: 1.8mm high-quality cold-rolled steel door body (optional 304 stainless steel), internal well-shaped reinforced frame, anti-deformation strength ≥1200kg/m²Intelligent control system
Silent drive: 24V DC brushless motor (0.5-1.2kW), noise ≤42dB (A-weighted), daily operation frequency ≥500 times
Precise speed regulation: door opening speed 8-20cm/s steplessly adjustable , start-stop buffer distance <1.5cm
Interlocking function: supports DICOM protocol and synchronization with medical equipment, automatically locks the door when the radiation is emitted
