Therefore, mobile X-ray equipment is useful for patients who have difficulty with movement. However, staff are exposed to scattered radiation from the patient, and they can receive potentially harmful radiation doses during radiography. We estimated occupational exposure during mobile radiography using phantom measurements. Scattered radiation distribution during mobile radiography was investigated using a radiation survey meter. The efficacy of radiation-reducing methods for mobile radiography was also evaluated. The dose decreased as the distance from the X-ray center increased. When the distance was more than 150 cm, the dose decreased to less than 1 \u03bcSv. It is extremely important for radiological technologists (RTs) to maintain a sufficient distance from the patient to reduce radiation exposure. The spatial dose at eye-lens height increases when the bed height is high, and when the RT is short in stature and abdominal imaging is performed. Maintaining sufficient distance from the patient is also particularly effective in limiting radiation exposure of the eye lens. Our results suggest that the doses of radiation received by staff during mobile radiography are not significant when appropriate radiation protection is used. To reduce exposure, it is important to maintain a sufficient distance from the patient. Therefore, RTs should bear this is mind during mobile radiography.<\/jats:p>","DOI":"10.3390\/bioengineering10020259","type":"journal-article","created":{"date-parts":[[2023,2,16]],"date-time":"2023-02-16T02:04:03Z","timestamp":1676513043000},"page":"259","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Spatial Scattering Radiation to the Radiological Technologist during Medical Mobile Radiography"],"prefix":"10.3390","volume":"10","author":[{"given":"Kazuki","family":"Otomo","sequence":"first","affiliation":[{"name":"Course of Radiological Technology, Health Sciences, Tohoku University Graduate School of Medicine, 2-1 Seiryo, Aoba-ku, Sendai 980-8575, Japan"},{"name":"Department of Radiology, Tohoku University Hospital, 1-1 Seiryo, Aoba-ku, Sendai 980-8574, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5382-6346","authenticated-orcid":false,"given":"Yohei","family":"Inaba","sequence":"additional","affiliation":[{"name":"Course of Radiological Technology, Health Sciences, Tohoku University Graduate School of Medicine, 2-1 Seiryo, Aoba-ku, Sendai 980-8575, Japan"},{"name":"Department of Radiation Disaster Medicine, International Research Institute of Disaster Science, Tohoku University, 468-1 Aramaki Aza-Aoba, Aoba-ku, Sendai 980-0845, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Keisuke","family":"Abe","sequence":"additional","affiliation":[{"name":"Department of Radiology, Tohoku University Hospital, 1-1 Seiryo, Aoba-ku, Sendai 980-8574, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mana","family":"Onodera","sequence":"additional","affiliation":[{"name":"Department of Radiology, Tohoku University Hospital, 1-1 Seiryo, Aoba-ku, Sendai 980-8574, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tomohiro","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Department of Radiology, Tohoku University Hospital, 1-1 Seiryo, Aoba-ku, Sendai 980-8574, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masahiro","family":"Sota","sequence":"additional","affiliation":[{"name":"Course of Radiological Technology, Health Sciences, Tohoku University Graduate School of Medicine, 2-1 Seiryo, Aoba-ku, Sendai 980-8575, Japan"},{"name":"Department of Radiology, Sendai Kousei Hospital, 4-5 Hirose-machi, Aoba-ku, Sendai, 980-0873, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshihiro","family":"Haga","sequence":"additional","affiliation":[{"name":"Course of Radiological Technology, Health Sciences, Tohoku University Graduate School of Medicine, 2-1 Seiryo, Aoba-ku, Sendai 980-8575, Japan"},{"name":"Department of Radiology, Sendai Kousei Hospital, 4-5 Hirose-machi, Aoba-ku, Sendai, 980-0873, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0194-8795","authenticated-orcid":false,"given":"Masatoshi","family":"Suzuki","sequence":"additional","affiliation":[{"name":"Course of Radiological Technology, Health Sciences, Tohoku University Graduate School of Medicine, 2-1 Seiryo, Aoba-ku, Sendai 980-8575, Japan"},{"name":"Department of Radiation Disaster Medicine, International Research Institute of Disaster Science, Tohoku University, 468-1 Aramaki Aza-Aoba, Aoba-ku, Sendai 980-0845, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Masayuki","family":"Zuguchi","sequence":"additional","affiliation":[{"name":"Course of Radiological Technology, Health Sciences, Tohoku University Graduate School of Medicine, 2-1 Seiryo, Aoba-ku, Sendai 980-8575, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Koichi","family":"Chida","sequence":"additional","affiliation":[{"name":"Course of Radiological Technology, Health Sciences, Tohoku University Graduate School of Medicine, 2-1 Seiryo, Aoba-ku, Sendai 980-8575, Japan"},{"name":"Department of Radiation Disaster Medicine, International Research Institute of Disaster Science, Tohoku University, 468-1 Aramaki Aza-Aoba, Aoba-ku, Sendai 980-0845, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,2,16]]},"reference":[{"key":"ref_1","unstructured":"International Commission on Radiological Protection (ICRP) (2013).
