Abstract

The invention belongs to the technical field of radiation protection clothing, in particular to an ionizing radiation protection clothing. The protective clothing includes an inner layer structure, an outer layer structure and an intermediate layer structure; the intermediate layer structure is a coating structure, and the coating used is composed of the following components and parts by weight: 40-50 parts of erbium oxide, 10-20 parts of bismuth oxide 5-15 parts of nano titanium dioxide, 10-20 parts of water-soluble polyurethane, 20-30 parts of silicone gel, 1-5 parts of polyethylene glycol. The protective clothing of the invention has excellent performance in preventing ionizing radiation, especially the performance in preventing gamma rays.

Description

technical field [0001] The invention belongs to the technical field of radiation protection clothing, in particular to an ionizing radiation protection clothing. Background technique [0002] The damage effects of ionizing radiation on the human body mainly include the blood system, nervous system, immune system, skin, eyes and many other aspects. Long-term low-dose ionizing radiation has caused different degrees of damage to different systems of radiation workers (including blood system, nervous system, digestive system, endocrine system, immune system, skin, eyes, etc.), and with the extension of radiation time , the damage effect becomes more and more obvious. [0003] Although with the rapid development of science and technology, the anti-ionizing radiation technology has also been continuously improved, and the exposure dose of radiation workers in practice has gradually decreased. Both medical institutions / enterprises and radiation workers must attach great importanc...
