Description of Mobile X-ray Screen

Mobile X-ray screens—also known as mobile lead screens or radiation shielding screens—are critical pieces of radiation protection equipment found in medical radiology departments, imaging centers, operating rooms, and industrial non-destructive testing facilities. Utilizing high-density materials such as lead plates or lead-impregnated acrylic, these devices employ the principle of shielding to attenuate ionizing radiation—specifically X-rays—with the aim of protecting medical personnel, patients, and operators from unnecessary radiation exposure. Serving as a complement to fixed shielding installations, mobile screens—distinguished by their flexibility and convenience—act as a pivotal tool for implementing the "shielding" component of the three fundamental principles of radiation protection: time, distance, and shielding. Typically constructed from stainless steel or high-grade aluminum alloy, these screens feature excellent corrosion resistance, impact resistance, ease of cleaning, and an aesthetically pleasing design. Certain high-end models feature pure white frames that offer superior stain resistance, making them ideally suited for the rigorous disinfection environments found in hospitals. The interior is filled with standard-compliant, Grade 1 medical-grade pure lead plates (with a specific gravity of approximately 11.345 g/cm³) boasting a purity level exceeding 99.99%, thereby ensuring highly effective attenuation of scattered radiation. Furthermore, the screens incorporate high-transmittance lead glass or lead-impregnated acrylic panels. Under illumination at a wavelength of 500 nm, the light transmittance typically exceeds 80%, ensuring an unobstructed field of view for medical personnel; concurrently, at a tube voltage of 120 kV, the lead equivalent shielding value is no less than 0.5 mmPb, thereby effectively balancing the requirements for both visibility and radiation protection.

Application Scenarios for Mobile X-Ray Screen

Mobile X-ray protective screens are widely utilized in the following fields:

Medical Institutions: Radiology X-ray rooms, CT rooms, MRI rooms, interventional operating rooms (DSA), orthopedic operating rooms, dental clinics, bedside examinations in emergency departments, etc.

Industrial Sector: Industrial non-destructive testing rooms and areas requiring the isolation of radioactive sources within the nuclear industry.

Research and Education: Laboratories and educational demonstration venues involving radioactive isotopes or X-ray equipment.

Proper Usage of Mobile X-ray Screen

Placement: Position the shield between the radiation source and the personnel, ensuring that the area requiring protection is completely covered. Ensure that the bottom edges of the shield maintain an appropriate clearance from the floor to prevent obstruction of movement or the creation of a tripping hazard.

Distance Control: Despite the presence of shielding protection, the ALARA principle ("As Low As Reasonably Achievable") should still be strictly observed. Minimize the time personnel spend within the radiation zone as much as possible, and—conditions permitting—maximize the distance between personnel and the radiation source.

Secure Positioning: Once the shield has been moved to its designated location, be sure to engage the wheel brakes to ensure the unit remains stable and to prevent it from wobbling or tipping over.

Routine Maintenance and Inspection of Mobile X-ray Screen

Visual Inspection: Periodically inspect the surface of the protective screen for any damage or dents; pay particular attention to the lead glass observation window to check for cracks.

Integrity Verification: If damage to the protective layer or exposure of the lead shielding plate is detected, immediately discontinue use and promptly replace the affected components with materials that meet applicable standards to prevent radiation leakage.

Cleaning and Maintenance: Wipe down the frame and glass surfaces using a mild disinfectant; avoid the use of highly corrosive chemicals to extend the service life of the equipment and maintain hygiene.
