Objective: To measure and analysis the leakage dose of a medical accelerator and explore the method for the leakage dose level measurements of the accelerators for medical uses. Methods:A Startrack model QA detector was used to measure the leakage dose of a medical accelerator by using the methods in GBZ126-2011. Results:The maximum leakage dose in M area to maximum dose ratio is 0.07%and the average leakage dose in M area to maximum dose ratio is 0.04%. Conclusion: It is necessary to explore a method to measure the leakage dose level of medical accelerators by dose scanners.
