The aim was to determine if the dosimetric properties of these two films are comparable in megavolt photon beams. Materials and Methods: Comparison measurements included: calibration curves, heterogeneous phantom dose profiles, and nasopharynx dose distribution measurement. Results: 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. Conclusion: Dose distributions between both films showed good correlation and XR-RV3 film can be used in radiotherapy for quality control checks. SP - 149 EP - 152 AU - Setilo, I.
