Among various occupations, aviation crew members and medical workers are exposed to high levels of radiation from scattered rays. This study focused on developing clothing for shielding aviation crew members from natural radiation during air travel. Materials were selected considering their radiation-shielding properties. A tungsten double-layered composite yarn and a polyethylene terephthalate (PET) fiber fabric containing BaSO<jats:sub>4<\/jats:sub> were manufactured. The characteristics and shielding performances of the products were analyzed. Prototypes of a protective scarf (for shielding the thyroid gland) and apron (for shielding the torso) for flight attendants were produced. A lightweight fabric was produced that neither restricts the movement of the wearer nor causes them skin discomfort. The shielding performances of the tungsten composite and PET fiber fabrics containing BaSO<jats:sub>4<\/jats:sub> were 0.018 mmPb and 0.03 mmPb, respectively, demonstrating low-dose shielding that may be useful for protecting aviation crew members from scattered rays. The characteristics of the developed fibers are comparable to those of materials used in clothing production; therefore, low-dose radiation-shielding clothing could be manufactured for use in aviation, medical, and other industries.<\/jats:p>","DOI":"10.1038\/s41598-021-83272-3","type":"journal-article","created":{"date-parts":[[2021,2,11]],"date-time":"2021-02-11T11:03:58Z","timestamp":1613041438000},"update-policy":"https:\/\/doi.org\/10.1007\/springer_crossmark_policy","source":"Crossref","is-referenced-by-count":16,"title":["Double-layered fiber for lightweight flexible clothing providing shielding from low-dose natural radiation"],"prefix":"10.1038","volume":"11","author":[{"given":"Seon-Chil","family":"Kim","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun Sik","family":"Son","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"297","published-online":{"date-parts":[[2021,2,11]]},"reference":[{"key":"83272_CR1","doi-asserted-by":"publisher","first-page":"240","DOI":"10.1016\/j.actaastro.2010.08.009","volume":"68","author":"TS Jang","year":"2011","unstructured":"Jang, T.
