Description of Lead L-Block Shielding Screen

The lead L-block shielding screen is a high-efficiency personal protection and isolation device designed specifically for environments involving radioactive materials. Its exterior is typically clad in 304 stainless steel or finished with an electrostatic spray coating; the stainless steel finish offers an aesthetic appearance, corrosion resistance, and ease of cleaning and disinfection—meeting strict hygiene standards for medical settings—while the spray-coated finish provides various color options to better blend with the surrounding environment. The shielding core consists of electrolytic lead with a purity exceeding 99.99% or medical-grade lead sheeting. Lead possesses an exceptionally high density (approximately 11.34 g/cm³) and a high atomic number (Z=82), enabling it to effectively attenuate high-energy photons through mechanisms such as the photoelectric effect, Compton scattering, and pair production. A key feature is its unique L-shaped geometry; this design overcomes the limitations of traditional flat lead screens regarding the trade-off between visibility and operational convenience. Optimized through ergonomic principles, it offers operators an improved field of view and superior radiation shielding. The device is primarily used in fields such as nuclear medicine laboratories, radiology departments, and industrial non-destructive testing to block ionizing radiation—including X-rays and gamma rays—thereby safeguarding the health and safety of medical and technical personnel.

Application of Lead L-Block Shielding Screen

Interventional Procedures and Cath Labs: During prolonged fluoroscopy-guided procedures—such as cardiac or neuro-interventional interventions—L-shaped screens serve as temporary barriers, protecting assistants or nurses in non-sterile zones from scattered radiation.

Dentistry and Bedside Imaging: In space-constrained dental clinics or at the bedside in hospital wards, L-shaped screens allow for rapid deployment, providing immediate protection for staff working near the patient.

Nuclear Medicine Dispensing Stations: Used in conjunction with long-handled forceps and glove boxes, L-shaped screens are positioned around the work surface to create a localized high-protection zone for the dispensing of radiopharmaceuticals and the preparation of injections.

Maintenance and Usage Guidelines

Environmental Requirements: Store in a dry, well-ventilated area free from corrosive gases to prevent oxidation of the lead sheet or corrosion of the finish.

Cleaning and Maintenance: Regularly wipe the stainless steel surfaces with a mild detergent to keep them clean. Do not use strong acid or alkaline solvents, as these may damage the surface coating.

Periodic Inspection: Check that the caster brakes function correctly, inspect frame connections for looseness, and examine the lead sheet surface for damage or cracks. If the lead layer becomes exposed, discontinue use immediately and arrange for professional repair to prevent lead contamination.

Proper Positioning: Ensure the L-shaped opening faces the radiation source during use and adjust the angle according to the actual radiation distribution to achieve optimal shielding effectiveness.
