Description of Mobile X-ray Protective Screen

The mobile X-ray protective screen is a collective radiation protection device designed specifically for medical radiology departments, imaging centers, operating rooms, and emergency settings. The main body of the screen is constructed from high-density lead or lead-composite panels, utilizing the high atomic number of lead to block radiation penetration. A key performance indicator is the "lead equivalent"; typically, the transparent viewing window offers a lead equivalent of 0.5 mmPb to 1.0 mmPb (or higher), while the opaque frame section ranges from 1.0 mmPb to 2.0 mmPb. Studies indicate that the installation of compliant protective screens can reduce ambient radiation intensity by an average of 81.81%. Its primary function is to effectively absorb and scatter X-rays using high-density lead materials, thereby protecting medical personnel and patients from unnecessary radiation exposure. Featuring high mobility, the device adapts to diverse and complex clinical scenarios—such as bedside radiography, interventional procedures, and temporary shielding—making it an indispensable component of modern medical radiation safety systems.

Proper Usage

Positioning for Protection: Place the protective screen between the radiation source and personnel, ensuring the screen fully covers the area requiring protection and minimizing the distance between personnel and the screen.

‌Secure Positioning: Once in the designated location, lock the caster brakes to prevent the equipment from sliding.

‌Use with Personal Protective Equipment (PPE): As a collective protective device, the screen should be used in conjunction with PPE—such as lead aprons, thyroid collars, and leaded eyewear—to achieve optimal protection.

Maintenance and Precautions

Regular Inspection: Periodically inspect the screen for damage. Focus checks on the integrity of the lead sheet (looking for cracks), the condition of the lead glass (checking for breakage), and the smooth operation of the casters. If damage is found, discontinue use immediately and replace the affected components with compliant materials.

‌Cleaning and Disinfection: Clean the surface using a mild detergent; avoid highly corrosive solvents to preserve the integrity of the coating and the lead glass.

‌Safety Clearance: Pay attention to the gap between the bottom edge of the screen and the floor during use; if necessary, attach a lead curtain to seal the gap and prevent radiation leakage from below.
