Objective: This study aimed to evaluate the feasibility of calibrating radiochromic films using different types of radiation. By comparing photon, electron and proton beams, we assessed whether calibration can be performed without relying on clinically restricted medical beams. Methods: Radiochromic films were irradiated with photon, electron and proton beams, each delivering a fixed dose in the 1-14 Gy range. The response of three colour channels - red, green and blue - was analysed. Calibration curves were established for each channel, and their sensitivity and consistency across different beam types were compared. Results: Among the three channels, the green fraction showed the highest sensitivity to ionising radiation. Its intensity calibration was consistent across all investigated beam types, indicating that the response of the green channel is independent of the radiation quality. Conclusions: Radiochromic film calibration can be reliably performed using photon, electron or proton beams. Since the green channel provides stable and reproducible results, any of these radiation sources can be used for calibration. This finding removes the need for exclusive access to clinical medical beams, simplifying the calibration process and improving accessibility for research and quality assurance applications.
