However, scattered radiation generated during imaging can lead to unnecessary radiation exposure for adjacent neonates and healthcare workers. Conventional mobile shielding devices are often challenging to implement effectively in NICU environments due to limited space and workflow constraints. Consequently, this study developed a foldable lead curtain that can be attached to a mobile X-ray unit and evaluated experimental measurements and Monte Carlo simulations. The lead curtain features a foldable acrylic panel structure that contains 0.15\u2005mmPb shielding material and is designed for attachment to a mobile X-ray unit. Shielding efficiency experiments showed that the lead curtain reduced scattered radiation by 91.1% at a distance of 50\u2005cm when positioned directly in the scatter path. At distances of 100\u2005cm and 150\u2005cm, the shielded readings fell below the detection limit of the ionization chamber dosimeter. Notably, significant dose reductions were observed even under the relatively low shielding condition of 0.15\u2005mmPb. These findings suggest that the proposed attachable foldable lead curtain may serve as a practical auxiliary radiation protection device for reducing scattered radiation exposure to adjacent neonates, which often face substantial spatial limitations.<\/jats:p>","DOI":"10.1177\/08953996261492737","type":"journal-article","created":{"date-parts":[[2026,10,13]],"date-time":"2026-10-13T06:17:23Z","timestamp":1791872243000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Evaluation of radiation dose reduction effect of a foldable attached lead curtain in portable X-ray examinations in the neonatal intensive care unit: A Monte Carlo simulation study"],"prefix":"10.1177","author":[{"given":"Hyemin","family":"Park","sequence":"first","affiliation":[{"name":"Masan University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hwieun","family":"Jeong","sequence":"additional","affiliation":[{"name":"Hanseo University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Donggeon","family":"Lim","sequence":"additional","affiliation":[{"name":"Hanseo University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daae","family":"Kim","sequence":"additional","affiliation":[{"name":"Hanseo University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chaewon","family":"Bae","sequence":"additional","affiliation":[{"name":"Hanseo University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5395-2916","authenticated-orcid":false,"given":"Ajin","family":"Jo","sequence":"additional","affiliation":[{"name":"Korea University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7322-9418","authenticated-orcid":false,"given":"Eunhye","family":"Kim","sequence":"additional","affiliation":[{"name":"Hanseo University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2026,10,12]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.17946\/JRST.2018.41.5.397"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1097\/00005373-199405000-00018"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.7742\/jksr.2013.7.2.113"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.3233\/XST-211091"},{"key":"e_1_3_2_6_2","first-page":"19","article-title":"Current status of neonatal intensive care in Korea","volume":"1","author":"Shin SM","year":"1997","unstructured":"Shin SM.
