Analysis of the Radiation Protection Principle of Medical Lead Plates

In fields such as medical and industrial flaw detection, radiation protection is a crucial aspect of safeguarding personnel health. Medical lead plates, as a core protective material, have received considerable attention for their radiation protection principle. Shandong Qite Radiation Protection Engineering Co., Ltd., a major domestic manufacturer of radiation protection equipment, provides a detailed analysis of the radiation protection secrets of medical lead plates.

Medical lead plates block the radiation emitted by radioactive materials, not the materials themselves, and have a precise protection logic for different types of radiation. For alpha rays with weak penetrating power, medical lead plates can completely block them. For beta rays with moderate penetrating power, lead plates can intercept the vast majority of rays, and it is recommended to use them in conjunction with low atomic number blocking materials to avoid bremsstrahlung radiation. Gamma rays, which accompany alpha and beta rays, have extremely strong penetrating power and require proportional blocking through lead plates of specific thickness; their protective effect is closely related to the thickness of the lead plate.

This protective property stems from lead's core physical properties: lead (chemical symbol Pb) has an atomic number of 82, making it the metal with the highest atomic number among stable chemical elements. Its density reaches 11.34 g/cm³, and its extremely strong resistance to radioactive penetration makes it a preferred material for radiation protection. Medical lead plates, as a silvery-gray, lustrous heavy metal, not only possess excellent protective performance but also exhibit strong corrosion resistance and low conductivity. Their surface easily oxidizes to form a protective film of lead oxide or basic lead carbonate, effectively preventing further oxidation and extending their service life.

To ensure product quality, Shandong Qite's medical lead plates adhere to strict labeling standards: each lead plate is cast or printed with a trademark and batch number, and the grade is marked with durable paint. Each bundle of products also has a prominent label clearly indicating the manufacturer, product name, grade, and other key information. The company has deep expertise in the field of radiation protection, with products covering lead plates, lead bricks, lead glass, lead doors, etc., forming a standardized, serialized, and comprehensive system. It collaborates with research institutions on innovation for a long time, providing high-quality products to safeguard radiation protection for various industries.
