Portable movable shielding device for gamma-ray flaw detection

The invention relates to a portable movable shielding device for gamma-ray flaw detection. By adopting the shielding device provided by the invention, effective shielding protection can be provided for nondestructive testing operators. According to the invention, a compact modular design is adopted, and the adjacent annular shielding modules are nested and connected through the convex parts and the concave dovetail grooves, so that a sufficient shielding space can be provided for workers, ray leakage between the annular shielding modules can be effectively avoided, and protection is more comprehensive and thorough; and radiation harm of gamma rays to operators is eliminated to the greatest extent. The shielding device provided by the invention has portability, the arrangement of the multiple layers of annular shielding modules and the movable bracket facilitates rapid transfer, assembly and disassembly, the workload of carrying the annular shielding modules on site is reduced, and the working efficiency is ef
