Description of Mobile PET Lead Shield

The Mobile PET Lead Shield is a high-performance radiation protection device designed specifically for nuclear medicine departments, PET/CT centers, and radiotherapy rooms. It utilizes a core shielding layer of high-density pure lead or lead-composite materials, leveraging lead's high atomic number to absorb and scatter gamma rays. Depending on protection requirements, lead equivalent options ranging from 0.5 mmPb to 2.0 mmPb (or higher) are available; these ensure significant attenuation—exceeding 80%—of the 511 keV gamma rays emitted by common PET radionuclides such as Fluorine-18. Equipped with heavy-duty, silent casters and locking mechanisms, the unit allows for easy mobility between patient rooms, injection rooms, waiting areas, and scanning suites. It can be fitted with a lead-glass viewing window, enabling medical staff to monitor patients or perform injections in real-time without radiation exposure. The structure is robust, easy to clean and disinfect, and compliant with hospital infection control standards; some models feature foldable or telescopic designs to save storage space. It is particularly well-suited for bedside care, emergency procedures, or scenarios requiring temporary radiation source isolation, addressing dynamic protection needs that fixed shielding walls cannot cover. The device effectively blocks high-energy gamma rays generated by radiopharmaceuticals (such as ¹⁸F-FDG) used in PET scans, protecting medical staff, patients' families, and the general public from unnecessary ionizing radiation exposure while maintaining operational flexibility and convenience.

Key Application Scenarios of Mobile PET Lead Shield

Radiopharmaceutical Injection Area: Serves as an immediate protective barrier for medical staff while administering PET imaging agents to patients.

Patient Waiting and Rest Area: Used to isolate patients who have just received injections, thereby reducing radiation exposure to others nearby and alleviating public anxiety regarding "mobile radiation sources."

Bedside Examination and Care: Provides localized radiation shielding during portable imaging or nursing procedures in inpatient wards.

Nuclear Medicine Waste Storage: Used in conjunction with other measures to provide an additional layer of protection for the short-term storage of radioactive waste.
