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/m²
Intelligent 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
Safety protection system
Active anti-pinch protection
12-beam infrared light curtain on both sides (vertical coverage 5-190cm, response time ≤0.08 seconds)

Certification and service
Durability guarantee:
Shielding attenuation <3% after 100,000 opening and closing tests
Track system life ≥300,000 times (wear tolerance ≤0.1mm)
Maintenance commitment:
3-year warranty for core components, free radiation leakage detection once a year (in compliance with JJG 774-2022)
Typical application scenarios
Hospital radiology department, dental CBCT room, industrial X-ray detection line, scientific research institution irradiation room
Selection guide:
The door opening size, equipment tube voltage (kV value), and daily traffic flow must be provided, and the engineer will calculate the optimal lead equivalent and motor power.
