fa Radiation Biology Radiation Biology گزارش کوتاه Short Report <p style="text-align: justify;"><strong>Background: </strong>&nbsp;Radiochromic film is used for radiation dose measurement, XR-RV3 is used in fluoroscopy and EBT2 film in radiation therapy. The aim was to determine if the dosimetric properties of these two films are comparable in megavolt photon beams. <strong>Materials and Methods:</strong> Comparison measurements included: calibration curves, heterogeneous phantom dose profiles, and nasopharynx dose distribution measurement. <strong>Results: </strong>Both film types required 24 hours to stabilize. Their heterogeneous phantom dose profiles were similar, and their dose distributions for a nasopharynx treatment were within 3%/3mm.<strong> Conclusion:</strong> Dose distributions between both films showed good correlation and XR-RV3 film can be used in radiotherapy for quality control checks.</p> <p></p> XR-RV3, EBT2, Calibration curves, heterogeneous 149 152 http://ijrr.com/browse.php?a_code=A-10-1-612&slc_lang=fa&sid=1 I.
