The energy of scattered radiation in medical clinical sites is important for estimating the biological effects of occupational exposure. Recent years have seen many reports on the dose of scattered radiation by IVR, but few on the energy spectrum. In this study, the energy spectrum of scattered X-rays was measured by using a cadmium telluride (CdTe) semiconductor detector during IVR on several neurosurgical and cardiovascular cases. The cumulated spectra in each case were compared. The spectra showed little changes among neurosurgical cases and relatively large changes among cardiovascular cases. This was assumed to be due to the change of X-ray tube voltage and tube angle was larger in cardiovascular cases. The resulting energy spectra will be essential for the assessment of detailed biological effects of occupational exposure.<\/jats:p>","DOI":"10.1093\/rpd\/ncad290","type":"journal-article","created":{"date-parts":[[2023,12,1]],"date-time":"2023-12-01T11:21:11Z","timestamp":1701429671000},"page":"181-186","source":"Crossref","is-referenced-by-count":2,"title":["Energy spectrum measurement of scattered X-rays during IVR procedure"],"prefix":"10.1093","volume":"200","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8061-0797","authenticated-orcid":false,"given":"Joma","family":"Oikawa","sequence":"first","affiliation":[{"name":"Graduate School of Health Sciences, Hokkaido University , N12-W5, Kita-ku, Sapporo 060-0812 , Japan"},{"name":"Department of Radiology, Sapporo Shuyukai Hosipital , 6-2-1, Shinhassamu 5-jo, Teine-ku, Sapporo 006-0805 , Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jun","family":"Sakai","sequence":"additional","affiliation":[{"name":"Department of Radiology, Sapporo Shuyukai Hosipital , 6-2-1, Shinhassamu 5-jo, Teine-ku, Sapporo 006-0805 , Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yusuke","family":"Fujiwara","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Sapporo Shuyukai Hospital , 6-2-1, Shinhassamu 5-jo, Teine-ku, Sapporo 006-0805 , Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kota","family":"Tsurusawa","sequence":"additional","affiliation":[{"name":"Department of Radiology, Sapporo Higashi Tokushukai Hospital , N33-E14, Higashi-ku, Sapporo 065-0033 , Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daisuke","family":"Shimao","sequence":"additional","affiliation":[{"name":"Department of Radiological Technology , Faculty of Health Sciences, , 15-4-1, Maeda 7-jo, Teine-ku, Sapporo 006-8585 , Japan"},{"name":"Hokkaido University of Science , Faculty of Health Sciences, , 15-4-1, Maeda 7-jo, Teine-ku, Sapporo 006-8585 , Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Date","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University , N12-W5, Kita-ku, Sapporo 060-0812 , Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiroyuki","family":"Sugimori","sequence":"additional","affiliation":[{"name":"Faculty of Health Sciences, Hokkaido University , N12-W5, Kita-ku, Sapporo 060-0812 , Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2023,11,30]]},"reference":[{"key":"2024021907513373700_ref1","doi-asserted-by":"crossref","first-page":"97","DOI":"10.1269\/jrr.09112","article-title":"Radiation dose and radiation protection for patients and physicians during interventional procedure","volume":"51","author":"Koichi","year":"2010","journal-title":"J.
