ところで、特許文献1、2に記載のような放射線防護用品は、放射性物質が飛散する環境下で使用すると、放射線防護用品が汚染(放射線防護用品に放射性物質が付着)し、使用を続けると、放射線防護用品の汚染が進んでいく。そこで、放射線防護用品の使用後に放射線防護用品を洗濯して除染する(付着した放射性物質を洗い落とす)ことが考えられる。しかしながら、放射線防護用品を洗濯すると、過度に湾曲したり折れ曲がるなどして、放射線防護用品が破損する虞がある。このため、放射線防護用品は、ある程度の回数を使用すると、廃棄処分されていた。また、特許文献3に記載のような滅菌衣は、単に、放射線防護用品の上に着用するだけであるので、滅菌衣と放射線防護用品との間に放射性物質が侵入して、放射線防護用品が汚染される虞がある。このため、この滅菌衣を用いたとしても、放射線防護用品は、ある程度の回数を使用すると、廃棄処分する必要がある。   By the way, when the radiation protection articles as described in Patent Documents 1 and 2 are used in an environment where radioactive substances are scattered, the radiation protection articles become contaminated (the radioactive substances adhere to the radiation protection articles) and use continues. Contamination of radiation protection products is progressing. Therefore, it is conceivable to wash and decontaminate the radiation protection article after use of the radiation protection article (to wash away the attached radioactive material). However, when the radiation protection article is washed, the radiation protection article may be broken due to excessive bending or bending. For this reason, radiation protection products have been disposed of after a certain number of uses. In addition, since the sterile clothing as described in Patent Document 3 is simply worn on the radiation protection product, the radioactive substance intrudes between the sterile clothing and the radiation protection product, causing the radiation protection product to There is a risk of contamination. For this reason, even with this sterile clothing, radiation protection products need to be disposed of after a certain number of uses.

本発明は、上記課題を解決するためになされたものであり、放射線防護用品を汚染されていない状態に保ち、放射線防護用品を長期に亘って使用可能とすることができる放射線防護用品を提供することを目的とする。   The present invention has been made to solve the above problems, and provides a radiation protection article capable of keeping the radiation protection article free from contamination and enabling the radiation protection article to be used for a long period of time.

Finally, the cover portions 41 a and 41 b are spread in the outer cover 3. At this time, the covering portion 41a and the second covering portion 42 partially overlap each other at a portion corresponding to the left lateral side of the body, and the covering portion 41b and the second covering portion 42 are one each other at a portion corresponding to the right lateral side of the body. Parts overlap. According to this modification, in the configuration in which the covering parts 41a and 41b and the second covering part 42 are integrated, the covering parts 41a and 41b are connected to the second covering part 42 at the part corresponding to the shoulder. By providing the opening and closing jig 34 on the back of the cover 3, the outer cover 3 can be easily attached to the protective body 2. Further, when the shielding member 2 is manufactured by cutting it from the original member (one long shielding member), the covering portions 41a and 41b are connected to the second covering portion 42 at the portions corresponding to the sides, as compared with the configuration. Thus, narrow original members can be used. As a result, it is possible to use a relatively inexpensive commercially available base member having a narrow width, and the radiation protection article 1 can be provided at low cost. The opening and closing jig 34 may be Velcro (registered trademark). In addition, the outer cover 3 is a chuck (registered trademark) or Velcro (registered trademark) so that a portion corresponding to the front of the body and a portion corresponding to the back partially overlap each other at the portions corresponding to the left flank and the right flank of the trunk. It may be engaged with a trademark. Even with such a configuration, the covering portion 41a and the second covering portion 42 partially overlap each other in a portion corresponding to the left lateral side of the trunk, and the covering portion 41b and the second covering portion 42 correspond to the right lateral side of the trunk.
