This article investigates the dose response, energy response, postexposure growth, and polarizing effects of this film after exposure to ionizing radiation in the diagnostic energy range. The effect of bit depth on scanning was also investigated. Films were scanned using an Epson Expression 10000XL document scanner or an X\u2010Rite model 301 spot densitometer. Color channel analysis was performed. The film showed usable response in the air kerma range of 1\u20131000 cGy, although by 1500 cGy the film appeared saturated when using the red color channel on a document scanner. The film response varied by 11% between 60 and 96 kVp and 3.5% between 96 and 125 kVp for doses above 1 Gy. Postexposure growth was found to be approximately logarithmic and fairly stable after 24 h. Films stored under office lighting exhibited around twice the density growth compared with film stored in a dark environment. The film showed strong orientation dependence when scanned using a polarized light source. A 48 bit scan provided no increase in sensitivity over 24 bits. Gafchromic XR\u2010RV2 film is a radiochromic film ideally suited for measurement of wide dose ranges at diagnostic energies. The energy dependence of this film limits its accuracy for dosimetry of unknown energy beams. For the document scanners used in this study a 24 bit scan was more than sufficient compared to a 48 bit scan. This is likely to be the case for most document scanners where electrical noise prevents higher bit depths from increasing the sensitivity of measurements.<\/jats:p>","DOI":"10.1118\/1.3147141","type":"journal-article","created":{"date-parts":[[2009,6,26]],"date-time":"2009-06-26T22:24:03Z","timestamp":1246055043000},"page":"3050-3058","source":"Crossref","is-referenced-by-count":27,"title":["Characteristics of Gafchromic<sup>\u00ae<\/sup> XR\u2010RV2 radiochromic film"],"prefix":"10.1002","volume":"36","author":[{"given":"Andrew","family":"Blair","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Juergen","family":"Meyer","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2009,6,11]]},"reference":[{"key":"e_1_2_7_2_1","volume-title":"Christensen's Physics of Diagnostic Radiology","author":"Curry T.
