Radiation protection door

shieldedRF-shieldedx-ray protection

Product Introduction
Motorized heavy-duty nuclear magnetic shielding door designed for medical and research installations (MRI suites 3.0T, linear accelerators ≥10 MeV, BNCT, particle accelerators). Provides simultaneous attenuation of high-energy X/γ and neutron radiation and RF shielding to prevent leakage and protect personnel and sensitive equipment.

Product Performance

• Motorized solution for hospital MRI departments: RF shielding effectiveness ≥100 dB at 150 MHz in a 3.0T magnetic field; meets electromagnetic compatibility and anti-interference requirements for MRI systems.
• Solution for research laboratories: For high-frequency bands (e.g., >1 GHz) the door uses a multi-layer copper + aluminum composite construction with ventilation waveguide windows (cut-off frequency ≥2 GHz). Triple-fold door option available.

Technical Parameters
Manufacturing: seamless full welding on copper plates.
Contact resistance at door-frame joints: <0.01 Ω.
Insulation impedance: ≥1000 MΩ (tested at 500 V DC).
Load-bearing capacity (motorized): ≥500 kg.
Emergency release: manual emergency unlocking device provided.
Non-magnetic design: non-magnetic components (e.g., non-magnetic locks) to preserve magnetic field homogeneity.

Application Fields

• Radiology departments: Imaging and interventional services using X-rays, γ-rays and other ionizing radiation for diagnostic examinations.
• Radiation oncology departments: Localized therapeutic treatments using ionizing radiation including X-rays, electron and proton beams and radioactive sources.
• Nuclear medicine departments: Diagnostic and therapeutic use of radionuclides, combining imaging, treatment, research and teaching.
