Introduction: Many factors, such as PRESAGE ® composition, dose rate, energy, and type of radiation, temperature, etc., may effect on PRESAGE ® dosimeter response. The aim of this study was investigating the effect of temperature variation on response of PRESAGE ® solid dosimeter. Materials and Methods: In this study, a PRESAGE ® solid detector was fabricated. Ninety-four percent weight polyurethane, 5% weight carbon tetrachloride, and 1% weight leucomalachite green were used. Radiological and physical characteristics of PRESAGEs ®, such as mass density, electron density, and effective number atomic were obtained and compared with water. Response of PRESAGE ® dosimeter in temperatures −4, 10, 25, 35, 45, 55, 65, 75, 85, and 90°C was evaluated. In addition, the absorption peak at various temperatures was investigated. Results: The results showed that the absorption peak at different temperatures was in the range of 630–635 nm. For temperatures below 75°C, the results indicated that temperature variation has no effect on the response of PRESAGE ® dosimeter whereas at the temperatures >75°C, temperature variation has an effect on PRESAGE ® dosimeter response. Conclusion: The finding showed that temperature changes have not impact on the absorption peak. In addition, the results related to the effect of temperature variation on the response of PRESAGE ® dosimeter showed that in the range of clinical applications (temperatures below 75°C), temperature variation has no effect on PRESAGE ® dosimeter response.
