Description of Desktop Lead Shielding Screen

A desktop lead shielding screen is a specialized safety device designed to block ionizing radiation, such as X-rays and gamma rays. It typically utilizes electrolytic lead sheeting with a purity of up to 99.994%. The thickness of the lead sheet is determined by the required "lead equivalent," with common specifications including 0.5 mm Pb, 1.0 mm Pb, and 2.0 mm Pb. Leveraging the high atomic number and high density of lead, the screen efficiently absorbs and attenuates penetrating radiation through mechanisms such as the photoelectric effect and Compton scattering. As X-rays pass through the lead sheet, their energy is progressively diminished, thereby significantly reducing the radiation intensity reaching human bodies or sensitive instruments. Studies indicate that the installation of a compliant shielding screen can reduce the average air kerma rate at surrounding measurement points by more than 80%, ensuring radiation levels fall within national safety standard limits. As essential infrastructure for medical radiology departments, imaging centers, dental clinics, and industrial flaw detection facilities, its core function is to absorb and scatter radiation using high-density lead material; this effectively lowers the radiation dose received by medical personnel and patients, creating a safe environment for diagnosis, treatment, and work.

Application Scenarios for Desktop Lead Shielding Screen

Radiology/Imaging Center: Protection during DR- or CT-guided puncture procedures.

Dentistry: Protection for practitioners and patients during panoramic dental imaging or periapical radiography.

Operating Room/Emergency Department: Temporary shielding during intraoperative fluoroscopy with C-arm systems.

Nuclear Medicine: Localized protection during the dispensing and injection of radiopharmaceuticals.

Industrial Radiography: Isolation of personnel during on-site X-ray non-destructive testing.

Laboratory: Background radiation shielding for low-background measurement environments, or localized protection at workstations for handling radioactive samples.
