Engineering Risks & FAQ - **Caution**: - **Caution**: - **Caution**: ### Q: What is the typical photon energy range for this medical linear accelerator? **A**: The photon energy range is typically 6 to 18 MV, as listed in the directory. However, the exact range depends on the specific model and configuration. Always confirm with the manufacturer. ### Q: What are the operating temperature and humidity requirements? **A**: The operating temperature should be between 15°C and 30°C, and relative humidity should be 20% to 80% non-condensing. These conditions are necessary for optimal performance and safety. ### Q: What standards are referenced for leakage radiation and dose uniformity? **A**: Leakage radiation is referenced to IEC 60601-2-1, and dose uniformity is referenced to IEC 60976. These standards are procurement references; compliance must be verified with the manufacturer. ### Q: What is the positioning accuracy of the system? **A**: The mechanical isocenter positioning accuracy is ±0.5 mm. This ensures precise targeting of tumors while minimizing damage to healthy tissue. Verify the actual accuracy for the specific model. ## 6.
