Description

Technical Field

[0001] The invention relates to a protective clothing for nuclear industry flaw detection and a processing technology thereof. Background Art

[0002] Nuclear radiation protective clothing is also called radiation protective clothing. It is special clothing developed specifically for protecting against X and gamma rays. Nuclear radiation protective clothing has many styles according to different working environments, including closed type, one-piece type, white coat type, etc.

[0003] In the prior art, protective clothing generally uses tantalum mesh or lead mesh alone for radiation protection. Although the tantalum mesh alone is low in price, it cannot block high-energy rays. Although the lead mesh alone can block most rays, it is expensive and easily affected by moisture. Therefore, it cannot meet public needs. At the same time, existing protective clothing cannot detect the amount of radiation in the environment in real time. Summary of the invention
