Nuclear magnetic shielding

Product Introduction

Heavy-duty radiation shielding doors engineered for applications such as medical linear accelerators (≥10 MeV), Boron Neutron Capture Therapy (BNCT), and particle accelerators. Their core function is to provide simultaneous shielding against high-energy x /γ rays and neutron radiation, preventing radiation leakage and ensuring the safety of personnel and the environment.

Product Performance

OR MotorizedFor Hospital MRI Department：Shall achieve a shielding effectiveness of ≥ 100dB at 150MHz in a 3.0T magnetic field environment, and meet the anti-interference compatibility requirements of the equipment.
For Scientific Research Laboratories：For high-frequency bands (e.g., above 1GHz), the shielding system shall adopt a multi-layer metal composite structure (copper + aluminum), equipped with ventilation waveguide windows (cut-off frequency ≥ 2GHz). Triple-fold Door.

Technical Parameters

Process Requirements：Copper plate welding shall adopt seamless full welding.	Contact Resistance ：Contact resistance at the joints between the door and door frame<0.01Ω
Insulation Impedance ：≥ 1000MΩ (tested at 500V DC).	Load-bearing Capacity：The motorized door features a load-bearing capacity of ≥500kg.
Emergency Unlocking ：Equipped with a manual emergency release device.	Non-magnetic Design：Non-magnetic components (e.g. non-magnetic locks) are adopted to prevent magnetic materials from affecting the magnetic field uniformity.

Application Fields

Department of Radiology：The Department of Radiology is a comprehensive department integrating imaging diagnosis and interventional therapy. Radiological diagnosis employs X-rays, gamma rays and other radiation to penetrate the human body, rendering images of internal bodily structures and organs on fluorescent screens or radiographic films, enabling evaluation of human anatomical morphology, physiological functions and pathological lesions.

Department of Radiation Oncology：Radiation oncology is a localized therapeutic modality that uses ionizing radiation for cancer treatment. Radiation sources include alpha, beta and gamma rays emitted from radioactive isotopes, as well as X-rays, electron beams, proton beams and other particle beams generated by various X-ray therapy units and medical accelerators.

Department of Nuclear Medicine：It adopts nuclear science technologies for disease diagnosis and treatment. As an integrated department combining imaging, therapeutic services, scientific research and teaching, it serves as one of the core modalities in modern medicine.
