The unique advantage of far\u2010UVC technology over traditional UV germicidal irradiation lies in the potential for direct application of far\u2010UVC into occupied spaces since antimicrobial doses of far\u2010UVC are significantly below the recommended daily safe exposure limits. This study used a ceiling\u2010mounted far\u2010UVC fixture emitting at 222\u2009nm to directly irradiate an indoor space and then evaluated the doses received upon a manikin. Radiation\u2010sensitive film was affixed to the head, nose, lip and eyes of the manikin, and the 8\u2010h equivalent exposure dose was determined. Variables examined included manikin height (sitting or standing position), manikin offset from directly below the fixture, tilt of the manikin, the addition of glasses, the addition of hair and different anatomical feature sizes. Importantly, at the manikin position with the highest dose to eyes, the average eye dose was only 5.8% of the maximum directly measured dose. These results provide the first experimental analysis of possible exposure doses a human would experience from an indoor far\u2010UVC installation.<\/jats:p>","DOI":"10.1111\/php.13671","type":"journal-article","created":{"date-parts":[[2022,7,12]],"date-time":"2022-07-12T03:19:12Z","timestamp":1657595952000},"page":"160-167","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":20,"title":["Ocular
